Plot synopsis:
CIA agent XK-150 (Robert Towne) is working undercover in a Cuba-like small Caribbean island nation that is undergoing a revolution when he discovers that notorious international playboy, promoter and mobster Renzo Capeto (Anthony Carbone) is planning something with a group of military types loyal to the deposed regime. XK-150 learns that the loyalists leader Colonel Tostada (Edmundo Rivera Alvarez) has liberated the contents of the national treasury and plans to flee the country with the money so that he and his fellow loyalists can plan a counter revolution. Capeto is providing the boat with which the Colonel, his men and the money can leave the island. So, XK-150 posing as Sparks Moran, a notorious gum machine burglar from Chicago, infiltrates Capeto's gang as he manages to get a job on board the boat. The other gang members include Capeto's lover Mary-Belle Monahan (Betsy Jones-Moreland) - a notorious moll who used to push hard drugs to schoolchildren. Her brother Happy Jack Monahan (Robert Bean)- a tennis bum and hired killer who has developed a muscle spasm in his cheek from watching too many Humphrey Bogart movies and finally Pete Peterson Jr. (Beach Dickerson) - Capeto's top henchman who was discovered at Jones Beach where he worked as a pickpocket and has an incredible ability to mimic animal noises.The gold is loaded onto the boat along with the Colonel and his soldiers and they set off headed for the United States. However, Renzo Capeto and his gang have other ideas. Sparks discovers that they plan to make up a story about the fantastical Creature of the Haunted Sea in order to persuade the Colonel to allow them to divert the boat towards San Juan. The Capeto gang will then bump off the Colonel and his men so that they can steal the money for themselves. Agent XK-150 constructs a radio out of hot dog sausages and pickled gherkins in order to relay a message about their plans to the CIA, but sadly has to eat it in order to avoid detection. The Colonel is suitably frightened by their stories of a legendary sea monster and agrees to the ship changing course. The gang's plan seems to be working as they begin to eliminate the Colonel's men and blame their deaths on the creature.However, unbeknownst to anyone aboard the boat the Creature of the Haunted Sea is actually real and following them.

Once he realises that the creature is real Capeto is forced into a sudden change of plan. He evacuates his crew to the island and sinks the boat in 30ft of water so that he and has gang can wait the creature has moved on then use scuba gear to go and retrieve the gold. Whilst on the island Pete Peterson meets and falls in love with a beautiful young woman Mango (Sonya Noemi Gonzalez) who can only communicate in sound effects. Sparks also discovers a phone booth on the deserted island that he can use to phone his reports back to HQ.
