A group of twenty somethings meet after a long time, and head to an island for a getaway, class reunion, and a night of partying. During the fateful evening the past begins to haunt them and old grudges from their shared past come to surface. As the night turns awry, they start to fear there might also be something else on the island besides them. During one bloody night old scores are settled, everything is brought to the surface, and revenge is had.
Unfortunately the movie Insanity is not yet available on Disney Plus.
