Twenty-eight weeks after the spread of a deadly rage virus, the inhabitants of the British Isles have lost their battle against the onslaught, as the virus has killed everyone there. Six months later, a group of Americans dare to set foot on the Isles, convinced the danger has passed. But it soon becomes all too clear that the scourge continues to live, waiting to pounce on its next victims.

While 28 Weeks Later lacks the humanism that made 28 Days Later a classic, it's made up with fantastic atmosphere and punchy direction.

'28 Weeks Later' features characters engaging in irrational actions for plot convenience as detrimental to the story's realism. However, some appreciate the film's intense action sequences and performances, which offer entertainment and excitement. The use of such plot devices is common in horror movies to heighten suspense and advance the narrative.
