A British
tramp steamer named the SS
Glencairn is on the long voyage home from the West Indies to Baltimore, and then to England during
World War II. The crew is a motley, fun-loving, hard-drinking lot. Among them is their consensus leader, a middle-aged Irishman named Driscoll; a young Swedish ex-farmer, Ole Olsen; a spiteful steward nicknamed Cocky; a brooding
Lord Jim-like Englishman, Smitty; and a burly, thoroughly dependable bruiser, Davis. On a sultry night in a port in the West Indies, the crew has been confined to the ship by order of the captain, but Drisk has arranged to import a boatload of local ladies. The crew carouse until a drunken brawl breaks out and the ladies are ordered off the ship and denied any of their promised compensation. The next day the ship sails to pick up its cargo for its return trip to England. When the crew discovers that the cargo is high explosives, they rebel, but are easily cowed into submission by the captain and the ship sails. They are also concerned that Smitty might be a German spy because he is so aloof and secretive. After they assault Smitty and restrain and gag him, they force him to give up the key to a small metal box they have found in his bunk. Opening the box against Smitty's vigorous protests, they discover a packet of letters from Smitty's wife revealing the fact that Smitty has been an alcoholic, dishonorably discharged from the British navy. In the war zone as they near port, a German plane attacks the ship, killing Smitty in a burst of machine gun fire. Reaching England without further incident, the rest of the crew members decide not to sign on for another voyage on the
Glencairn and go ashore, determined to help Ole return to his family in Sweden, whom he has not seen in ten years. In spite of their determination to help Ole, the crew is incapable of passing up the opportunity for a good time drinking and dancing in a seedy bar to which they have been lured by an agent for ships looking for crew members. He has his eye on Ole because he is the biggest and strongest of the lot. He drugs Ole's drink, and his confederates
shanghai him aboard another ship, the
Amindra. Driscoll and the rest of the drunk crew rescue Ole, but Driscoll is clubbed and left on board as the crew makes its escape. The next morning, the crew straggles back to the
Glencairn to sign on for another voyage. A newspaper headline reveals that the
Amindra has been sunk in the Channel by German torpedoes, killing all on board. ==Cast==
