A Corpse Hung in the Web

On their way to a gig in Singapore, a troupe of beautiful dancers and Gary (their manager) plunge into the ocean aboard a plane with engines on fire. Adrift in a rubber raft for a week, they finally make landfall on a small island. After filling up on their first fresh water in a while, they discover a cabin with its only resident (a professor) hanging dead in a large spider web. The island has natural uranium deposits that have given rise to a race of large, wicked spiders. One of these bites Gary and turns his head into a spider-faced monster with three fangs. Now infected with the spider venom, he attacks others in the part, strangling them. Two men, Joe and Bobby, appear aboard a mining company support boat with periodic supplies for the professor. They like being the only men such a gorgeous bevy of girls. Bobby is playing the field among them. Later, while out for a walk, he is caught and strangled by Gary. Eventually, the survivors learn that the spiders and Gary are afraid of fire. Joe grabs a box of flares and works with the girls to overcome Gary. They use mining company boat to escape back to civilization.
