Captain Carey (Tab Hunter) is tasked with transporting an underwater demolition team to Bikini Atoll which is held by the Japanese, and a US Navy submarine with top secret technology is currently sunk on the seabed and must be blown up before the Japanese can find it. Among the demolition team is Malzone (Frankie Avalon) who dreams of being a 1960s crooner and hanging out on a beach amongst young women!
This isn't a great film but it is a very strange one. The war scenes are not bad though the sort of anti-submarine warfare seen before (and probably better). The songs and weirdness take the film to a whole other level, which is either awful or brilliant or maybe a bit of both.
