Solitary is about a boy who mysteriously wakes up in an alley and discovers that every single person in the world has disappeared. Part of the film depicts his struggle to survive - stocking up on food, drinks, clothes and weapons etc. - until one day somebody else knocks at his door ... it is revealed that there are survivors scattered all over the place and that they must find each other if they want to live. But it soon becomes clear that one of them has his own agenda - and that he wants the world for himself ...
