Opening scene shows "Sister Sara" in compromising position with clothes half off and being harassed by a gang in the desert side of her breast and butt can be seen, implying attempted rape.

A fully clothed man removes his gun belt and climbs into the bubble bath with a woman, and it is implied that they have sex. No explicit nudity is seen.
