Elektra the warrior survives a near-death experience, becomes an assassin-for-hire, and tries to protect her two latest targets, a single father and his young daughter, from a group of supernatural assassins.

In the ultimate battle between good and evil stands a warrior who makes the choice that tips the balance. A strong, mysterious and a deadly sexy action heroine - a lethal synthesis of grace and power. Not long after recovering from seemingly mortal wounds, Elektra has severed all ties with the world, living only for her next assignment. But in an unexpected turn of events, she is forced to make a decision that can take her life in a new direction - or destroy her. Key players in Elektra's journey are Stick, a blind martial arts master responsible for Elektra's "resurrection," and Mark Miller and Abby Miller, a father and daughter on the run from The Hand, a powerful syndicate whose members practice the dark version of the martial art Kimagure.—Anthony Pereyra {hypersonic91@yahoo.com}

After the fateful events that changed her life in Daredevil (2003), Elektra Natchios has now transformed into a pitiless professional assassin for hire. For her next contract, Elektra has to take down the single father, Mark Miller, and his young daughter, Abby; however--for the first time in her blood-drenched career--serious doubts will pave the way for a change of plans. Now, the killer becomes the protector--and with the powerful henchmen of the nefarious criminal organisation known only as The Order of the Hand after them--Elektra must put her rigorous training in the ancient martial art of Kimagure to good use. Can Elektra appease the past and save her helpless targets?—Nick Riganas

Elektra, once a student of Kimagure, a force for good, whose masters can see the future and even bring people back from the dead, is now a paid assassin. The enemy, the force for evil, at this time is known as The Hand, whose members use the dark arts. In this tale Elektra is given an assignment to kill a man and his daughter. However when the time comes to complete the mission she is unable to. The daughter is also being sought by The Hand, for she is known as a treasure that can tip the scales in favor of either good or evil. The Hand, who have the policy of "If we can't have her then no one can", send their own people to kill her. Elektra then allies herself with the Millers and helps to protect them from The Hand. The journey to the climax, the ultimate battle between good and evil for the treasure, has some interesting revelations, heading for a finale with an interesting twist.—Andrew Brooks

The Hand is a crime syndicate that represents Evil in the present time. The good are represented by the followers of Kimagure, whose master's can resurrect the dead. The legends talk of a motherless daughter who will tip the balance between good and evil. She is the Treasure, and both sides seek her out.

After being killed in Daredevil, Elektra Natchios (Jennifer Garner) is revived by a blind martial arts master called Stick (Terence Stamp). She is brought to his training compound to learn Kimagure, an ancient martial arts discipline that provides its practitioners with precognition as well as the ability to resurrect the dead. Elektra is soon expelled because of her inability to let go of her rage. She leaves and uses her training to become a contract killer.

Years later, Elektra infiltrates a heavily guarded area, kills the guards, and manages to slay her target DeMarco (Jason Isaacs). The Hand pursues the Treasure. Master Roshi wants the Treasure captured, but his son Kirigi says that the Treasure must be eliminated if it cannot be acquired. It is decided to hire an assassin to eliminate the Treasure.

Elektra's agent McCabe (Colin Cunningham) receives an unusually large offer from an anonymous client wishing to hire Elektra's services. McCabe charges Elektra 10% commission for being the middleman and bringing her contracts. The only stipulation: she must spend a few days in a rented home on the island where the assassination is to be performed before the names of the targets are revealed. Elektra is shown to have OCD. Elektra has nightmares about being visited by ghosts when she was a child. Elektra's mother was killed, and Elektra took a locket from her body and keeps it with her at all times.

During the wait, Elektra finds a girl Abby (Kirsten Prout) who tried to swipe Elektra's necklace and Elektra sends her away. While meditating, Elektra meets and befriends Abby's father Mark Miller (Goran Visnjic). Abby later invites Elektra to dinner on Mark's behalf. Later that day, Elektra discovers that Abby, like Elektra herself, has obsessive-compulsive disorder. Elektra develops a romantic interest in Mark (whose wife had died in Baltimore in a car accident), but soon learns he and Abby are the targets she has been hired to kill. Elektra spares them and leaves, but later returns in time to protect them from assassins sent by The Hand, a crime syndicate of ninja mercenaries. Elektra has the ability to look into the future and is thus able to evade all attacks on her, which would have otherwise killed her.

Meanwhile, Roshi (Cary-Hiroyuki Tagawa), master of The Hand, learns of the failed attempt and permits his son Kirigi (Will Yun Lee) to lead a new team of assassins to kill Elektra and return with Abby, referred to as "The Treasure". Elektra tries to leave Abby and Mark with Stick, but he scolds her into protecting them herself. Mark reveals that he knows Abby is being hunted, and that The Hand killed his wife, while hunting for Abby. But Mark doesn't reveal the truth about Abby to Elektra, that Abby is The Treasure. Elektra then drives Mark and Abby to McCabe's country house, but is followed by Kirigi, Typhoid (Natassia Malthe), Stone (Bob Sapp), Kinkou (Edison T. Ribeiro), and Tattoo (Chris Ackerman). Elektra flees with Mark and Abby through a secret underground exit to the orchard, while McCabe sacrifices himself to allow them to escape.

Kirigi and the assassins hunt down Elektra, Mark, and Abby in the forest nearby. Elektra manages to kill Stone, while Abby and Mark kill Kinkou with one of his own daggers. As Elektra is distracted by the revelation that Abby has martial arts skills, Typhoid gives Elektra the "Kiss of Death". Abby is captured by Kirigi. Suddenly, Stick and his Chaste ninjas arrive, forcing Kirigi, Typhoid, and Tattoo to retreat. Stick manages to save Elektra from death and takes them under his protection.

Stick confirms Abby is a martial arts prodigy which is the "Treasure" of martial arts whom the Hand seek to use. Elektra learns that she was a Treasure herself and her mother was a casualty of the fight between The Chaste and The Hand with her as reason. She also learns that Stick set up the murder contract on Mark and Abby in order to test Elektra's propensity for compassion.

Elektra Astrally projects herself to a meeting with Kirigi and challenges him to a fight; the winner claiming Abby for their own purpose. Elektra returns to her childhood home to face Kirigi, and finally remembers he was her mother's killer. Elektra is defeated by Kirigi, but Abby arrives and engages him long enough for Elektra to recuperate. Elektra and Abby then escape and hide in a hedge maze but are separated when Abby is captured by snakes dispatched by Tattoo. Elektra finds Tattoo and kills him, saving Abby in the process. Elektra engages Kirigi a second time and manages to kill him. Typhoid poisons Abby, the same way she did to Elektra earlier, killing her in the process. Elektra kills Typhoid and successfully resurrects Abby, overcoming her rage.

When Mark comes to take Abby, he and Elektra kiss and go their separate ways. Just as Elektra leaves the grounds of her childhood home for the final time, she meets Stick and the two exchange words to each other. Elektra departs, knowing Abby and Mark will be safe.
