Serpent Island

An office secretary from Scranton, Pennsylvania (Mary Munday) sets out to find her great-grandfather's hidden treasure. She enlists the aid of a former Marine Engineer turned harbor bum (Sonny Tufts) and the greedy captain (Tom Monroe) of the sea ship "Constellation". They find the gold hidden on an island near Haiti, but it's guarded by a voodoo cult and a boa constrictor.
