A young Joan Collins sizzles as a desert island beauty being courted by George Cole, Kenneth More and Robertson Hare. Shipwrecked on an idyllic tropical island, heiress Sadie Patch (Joan Collins) quickly discovers that her fellow castaways are a pretty rum lot. There's Pat (Kenneth More), a rough and ready Irish stoker, Jimmy the journalist (George Cole) and half-baked old Professor Gibble (Robertson Hare). On a small island where the only other distractions are coconuts, fish and a naughty cockatoo, it isn't long before the three men notice Sadie's rather obvious charms. Life on their island paradise is about to get very uncomfortable - especially since Sadie has decided to start wearing a bikini everywhere! They swear a solemn oath not to compete for her affection but - one by one - each man finds his resolve weakened by Sadie's scorching sensuality. Let the best man win!
