Captain Ambrose comes from a long line of distinguished sailors                  but is all too susceptible to seasickness       After the war, he buys himself a nautical command on shore; a decrepit amusement pier at the British resort town Sandcastle-on-Sea, whose prim town council has outlawed arcade games as a form of gambling! Running the pier like a naval vessel, the captain's determination to make it a modern, going concern meets steady opposition       But with an unexpected new ally, he pursues a remarkable scheme to liberate his ship from land authorities
