Little Billy has been taken to the theater by his parents and as a result becomes stage-struck. At a children's party Billy plays stage manager and drills the children in some of the scenes he has witnessed. Later in the day while playing on the lawn the idea strikes him to play the drama with realism, so they go down to the shore and use a rowboat for a pirate ship, seizing his sister and placing her aboard. This is considered great, until the boat breaks from its mooring and little brother and sister are carried by the rough sea far out from the shore. As his parents are away on a visit to the city, It is some time before Billy can secure aid. Upon their return, papa, after an exciting sail in a motor boat, rescues them.
