In Springfield, Paul contaminates the supply of bottled water of the Down Home Water to the local high-school on the day of the prom. Alex (Rusty Kelley) convinces his friend Jonathan (Noah Segan), who has a crush on Cassie (Alexi Wasser) and is bullied by a school mate, to go to the prom. However, the contaminated water spreads a deadly flesh-eating virus among the students.

"Cabin Fever 2: Spring Fever" is a weak sequel, with a bad development of the plot and characters, gross and unpleasant. It seems that the writer was in a hurry to finish his work and was not careful with the story; or maybe Ti West was only interested in gore and special effects and used a "heavy hand" and the black humor never works. In the end, this rip-off "Carrie" with "Outbreak" (or any other movie of virus outbreak) is only nasty and not funny. My vote is five.

Title (Brazil): "Cabana do Inferno 2" ("Cabin of the Hell 2")
