The story centers on the charismatic sea captain Käpt'n Bay-Bay, portrayed by Hans Albers, who on his wedding day shares tales of his seafaring exploits with his wedding guests after an unexpected delay in the ceremony. The narrative employs a framing device where the captain, waiting at a tavern near the church, recounts through flashbacks his previous romantic misadventures and adventurous encounters at sea, blending humor, music, and exotic locales. These retrospective stories highlight his roguish charm and the obstacles that have shaped his life, all while the present-day celebration unfolds.
