(There are Spoilers) Surviving a violent Mediterranean Sea storm the skipper, Jurgen Prochnow, was unable to save the life of his friend and fellow seaman Paul Pelikan, Mario Stock, and his former, and now Mario's, lover Mona, Gvalyna Szapolowska. The Skipper hold's himself responsible for their deaths even though he was cleared of any wrong doing by a Seaman/Mariner Court.
Losing his nerve and getting drunk the Skipper hangs out all day and night, for six months, at the local Califorina Club drinking instead of going back out to sea on his ship the Bella Donna. Things change for the Skipper when he's approached by a young British duet of singer and dancer Su & Lou, Patsy Kensit & Elizabeth Hurley. The two are dying to get out of this boring ghost town of Gibraltar and sail to sunny and swinging Barbados in the West Indies. A trip of some 2,500 miles that would take over a month.
The Skipper needing a reason to go back to sea on his ship jumps at the idea that the girls proposed to him and the next day the Skipper together with Su & Lou and their pet pooch Willard sails past the "Pillars of Hercules" into the wide open and dangerous Atlantic Ocean. It turned out to be a voyage straight into hell.
Great scenic and ocean photography with a number of spectacular sunrise and sunsets can't overcome the film "Kill Cruise" unconvincing script and totally unbelievable surprise ending. The ending is so off-the-wall that it makes you wonder if you fell asleep while watching the film and missed something that would make it at least plausible to the movie's story.
A less then glamorous Elizabeth Hurley and down in the dumps-looking Patsy Kensit make up the trio, or quintet if you include the cute little dog Willard, on the cruise yacht Bella Donna. Thing start to get edgy when Su becomes jealous of the Skipper taking her friend, and possibly lesbian lover,Lou away from her as they both have a sexual tryst right in front of her. Su plans to murder the Skipper, as well as Lou, by first letting them drown at sea as they were both swimming, and making out underwater, by taking off with the boat Bella Donna. Later Su hides the insulin that the Skipper needs for his diabetic condition and his life is saved by Lou who finds it just in time, hidden by Su inside a world globe, just before in went into insulin shock.
With the crazed jealous and murderously inclined Su on deck the movie then immediately changes course where we see the three on board with Su & Lou dancing and singing as if everything that we saw up until then was forgotten about. Then were hit with an ending that's straight out of nowhere.
