An English-German filmmaking couple retreat to Fårö for the summer to each write screenplays for their upcoming films in an act of pilgrimage to the place that inspired Ingmar Bergman. As the summer and their screenplays advance, the lines between reality and fiction start to blur against the backdrop of the Island's wild landscape.

Tom Leimer arrives to the isle of Gotland, Sweden during the summer in order to find his old love Therese Sandström. She has, however, started a new life together with the upper-class-guy Karl von Silberhelm, and wishes no longer to know Tom because of his criminal past. A virus, turning people into living dead, breaks out on the isle. Tom makes his decision to try to rescue Therese - a choice that turns out to be more dangerous than he expected, since each who is infected hungers always for fresh human-flesh.
