Alice, the rightful heir to the throne of Bologna, flees from her domain because she is pursued by the Prime Minister, who has designs both upon her, and the kingdom. On the boat, she falls in love with Slim, a sailor boy, who does not respond to her advances because she is disguised as a boy. They all return in Bologna, where Slim becomes the knock-out kid of the Bolognas, single-handedly vanquishes the whole army, discovers Alice's disguise, and instead of strangling her marries her.
