The film stars actor Rod La Rocque as 'Jerry Cleggert', a good-natured descendant of an 18th-century pirate who resides aboard the rickety ship Jasper B. Cleggert is informed that in order to inherit a large inheritance, he must marry on his twenty-fifth birthday – otherwise he would relinquish all claims to his impending fortune.
Jerry soon meets his ideal would-be bride, Agatha Fairhaven (Mildred Harris), and the two immediately fall in love. Complications arise when the dastardly Reginald Maltravers (Snitz Edwards) attempts to cheat Agatha out of her inheritance.
The courting couple suffer a series of mishaps on the way to altar; they are waylaid en route by a trio of bandits, escape from a runaway taxi cab, and outrun a mob of unscrupulous state authorities.
The weary couple finally manage to wed just before the deadline on board the Jasper B and Cleggert inherits his family fortune.
