Hot Box, The (1972)

When four sexy nurses arrive in the tropics to work at a medical aid unit, they get more than they bargained for. The terror begins when they're kidnapped by a troop of ruthless bandits and subjected to all kinds of vulgar treatment. A rebel steals them away to care for his poverty-stricken people, and their luck begins to change. But not for long, as the girls are soon captured by a sadistic government official (Charles Dierkop), caged in a hot metal box and raped. Only the handsome rebel can save them. Also stars Andrea Cagan, Margaret Markov, Rickey Richardson and Laurie Rose.
