One Sunday morning, four men set out on a fishing trip. However, there is an ulterior motive for their expedition: one of the men is about to be framed for a crime of which he is totally innocent. Another of the men is a killer while the third is about to become one. And the fourth man is responsible for the whole grisly set-up. Once they have arrived at their destination, tensions between the group begin to rise and soon reach a murderous pitch.
