There's an 8-second sex scene where a woman is seen bouncing on a man (no nudity shown, but it's clear what they are doing). Scene then cuts to her in a bra and panties with part of her buttocks shown.
The story does involve themes of pimps and prostitues (only apart of the first act)
Prositutes are seen messaging a man on a cellphone and are later seen meeting up.
Several middle-aged or elderly men in a washhouse dressed only in loin cloths.
Only male nudity, men in loinclothes. Absolutely no female nudity.
