Fiend of Dope Island(1960)

He enslaved an island...and a woman!

Charlie is a dope smuggler who lives on his own private desert island and rules over the natives with an iron fist. When the native stooges get out of line, Charlie literally cracks the whip on his insubordinate subordinates. When a sexpot named Glory comes to the island, he holds her prisoner and makes her go-go dance for him.
