The teenagers (including June Kenney and Robert Reed) who are holidaying in a boat discover an island they think is deserted. Unfortunately, they soon discover the island is owned by the somewhat sinister Dr Balleau (Wilton Graff).
To the teenagers' horror they discover that anyone who lands on Balleau's island becomes his prey, he hunts them down and then turns them into macabre trophies...
This is a rather poor and tedious rip-off of the Most Dangerous Game (which isn't that brilliant either though leagues above this nonsense), it lacks much in the way of decent thrills or action. Nothing really makes any sense and the tiny budget doesn't really stretch to much.
