The Pool(2018)

No water. No ladder. No way out.

Left alone to clean up a 6-meter-deep deserted pool, Day falls asleep on an inflatable raft. When he wakes, the water level has sunk so low that he can't climb out on his own. Stuck in the pool, Day screams for help, but the only thing that hears him is a creature from a nearby crocodile farm.
