Popsy Pop(1971)

She'd do anything to help them with the heist... and then everything to keep the haul for her own little beautiful self!

Claudia Cardinale is Popsy, who double-crosses her older partner Silva (Stanley Baker). Silva has arranged to divert diamonds from a large corporate-run diamond mine in the South American jungle, and Popsy does her “pop” wrong as they are both pursued by police.
