Members of the Palisades Defense Corp. sales group arrive in Europe for a team-building exercise. A fallen tree blocks the route, and they must hike to their destination. However, a psychotic killer lurks in the woods, and he has a horrible fate in mind for each of the co-workers.
Unfortunately the movie Severance is not yet available on HBO Max.
