The motion picture chums at Seaside Park

Three enterprising boys arrive at a bustling seaside resort and secure a vacant boardwalk building to establish a motion-picture playhouse. They refurbish the space and confront money worries, managerial challenges, and stiff competition from rival shows while organizing staff and publicity. A series of dramatic episodes, including a kidnapping, technical experiments with a speaking picture and a prized film, and a destructive storm, test their resolve. Through practical problem-solving, loyal friendship, and a fortunate discovery that eases finances, they overcome setbacks and bring their theater to a successful opening and profitable operation.
