'Hell 6 Meters') is a 2018 Thai survival thriller film directed by Ping Lumpraploeng, starring Theeradej Wongpuapan and Ratnamon Ratchiratham.

[2][3] The film opens with a man named Day, who is lying in a drained pool with several injuries to his body.

The following morning, Day clears the pool of the props used for the photoshoot and relaxes on an inflatable raft, with Lucky tied to a leash nearby.

Not noticing the lowered water level, she jumps into the pool before Day can warn her, but she slips and hits her head on the diving board.

That night a crocodile appears and crawls towards Lucky but slips on some metal pipes by the side of the pool and falls in.

Day braves the drain tunnels and finds a small pumping station where a ladder leads to a locked grate on the surface above the pool.

Tension starts to arise between the two as they try and fail to escape from the pool, and after Day admits to feeling he would not be a good father, and to wanting Koi to have an abortion.

Seeing what he believes is a drone, Day leaves Koi in the pumping station and makes his way back to the pool, only to discover it's a remote-controlled glider.

He uses Lucky's body and leash to climb out of the pool and prys open the grate to the pumping station, rescuing Koi before she drowns.
