The beautiful Florida Keys provide the setting of this adventure that tells the tale of a fun-filled fishing trip that becomes a nightmare when the charter boat is wrecked on an isolated island. Unfortunately, there are very few provisions and the group must fend for themselves. They are eventually assisted by a hermit, but before that one of the group goes insane, and another is eaten by an alligator.
Unfortunately the movie Mercy Island is not yet available on HBO Max.
