底线

简和伴侣的森林之旅出了岔子，当一个陌生人出现并质疑他们关系的真实性时，她开始怀疑自己是否真正掌握了现实的全部真相。

　　Robbins is sentenced to prison for the assassination of his general officer, a prison you leave only when you die. Since nobody ever leaves the prison, nobody knows what the prison is like. The prison manager realizes this and buys himself an island playground called "Absolom," where the worst prisoners are free to create an isolated barbaric society, and where the strongest men rule...a living hell. Robbins is sent to Absolom after he almost kills the prison manager.

　　Six people bound together by a traumatic experience decide to round off a year of group therapy in style. They join each other once more, traveling up to the Scottish Lowlands for a reunion weekend in a 1970s holiday let. Soon a number of mysterious and horrifying events start to expose the cracks in their relationships, and one by one they discover that trust runs but skin-deep. A night of closure turns out to be far more final than they could have anticipated.
