1963, the height of the Cold War. In an unlikely alliance, a CIA agent, Napoleon Solo (played by Henry Cavill) and KGB agent, Illya Kuryakin (Armie Hammer), band together to save the world from nuclear disaster. A top nuclear scientist, formerly employed by the US, has gone missing. It is suspected his brother has kidnapped him to work on a nuclear bomb. Solo and Kuryakin accompany the scientist's daughter, Gaby (Alicia Vikander), to Rome, as this is where her uncle is based. The idea is to covertly investigate his company and, hopefully, find the scientist and the bomb. Things aren't all plain sailing though. This is heightened by the fact that Solo and Kuryakin aren't sure they can trust each other and, to some extent, still regard each other as enemies.

An entertaining action-espionage caper. Decent plot, though a tad basic and formulaic. Some great, humorous banter, and that's what elevates the movie above the average spy or action movie.

Solid performances from Henry Cavill and Armie Hammer in the lead roles. The stand out performance, however, is from Alicia Vikander who is delightful as Gaby.

The cast also includes Hugh Grant and Elizabeth Debicki, and neither of them disappoint.
