They Remain (2018)

There is some minor non-sexual nudity including female breasts and male buttocks.

A woman straddles a man and they kiss heatedly. They then have sex but it is implied rather than shown directly.

A man's testicles are clearly, but briefly seen.

A man has acid splashed on his face.

A man is shown supine with a severe bloody gash in his chest. You can only see blood but he looks badly hurt. This is part of a larger sequence in which a flower-child cult dances and waves knives around.
