Movies like The Pool

Day, an insecure art director of a commercial production company is left alone to clear up a 6-meter deep deserted pool after the shooting. He falls asleep on an inflatable raft due to an unbearable fatigue. When he wakes up again the water level has sunk so low that he cannot climb out of the pool on his own. He screams for help but the only thing that hears him is some creature from a nearby crocodile farm.
