Tony and Felix own a tramp boat, and sail around the Caribbean doing odd jobs and drinking a lot. They agree to ferry the beautiful but passportless Irena to another island. They both fall for her, leading to betrayal and a break-up of their partnership. Tony takes a job on a cargo ship. After a collision he finds himself trapped below deck with time running out (the ship is aflame), and only Felix, whom he hates and has sworn to kill, left to save him.
Unfortunately the movie Fire Down Below is not yet available on HBO Max.
