Comedy directed by Peter Medak. Having learned where the captain has hidden his treasure, a pirate betrays and kills him in order to take the loot for his own. He vows to return and claim the treasure, but when he does he soon finds his memory is failing him and he cannot remember where the loot is hidden. To find it, he'll need the ghostly assistance of the very captain he so treacherously slew. But it won't be simple to get him on board, not with another buccaneer captain showing up and meddling and a vengeful first mate pursuing him. The cast includes Peter Sellers, Spike Milligan and Clive Revill.
