A sequel to 28 days later and you don't need to watch it to understand this one. The infection has died off and the UK population has been reduced to a few, being backed by US forces living on the Isle of dogs in London. We follow one family haunted by what they saw in the outbreak, some of these demons return. You rarely see the aftermath of an apocalypse with this interesting premise and conflicted characters it really starts well. But once the inevitable returns so does the usual clichés in this genre.
