When his attempt fails, Donna punches him; as he falls, Birkhead accidentally releases a bomb, which rolls against the conference's grandstand and explodes, though Stilwell and the crowd escape unhurt. At the Santa Monica oceanside home of her father Ward Douglas and his wife Joan, Betty and her friend Maxine Dexheimer, who have just become USO hostesses, tell Wally that they are only allowed to dance with servicemen as they are now the only male patrons allowed in the club. Wally hides in the garage when Ward, who disapproves of him, appears. Sgt. Tree and his crew arrive and inform Ward and Joan that the army wants to install an anti-aircraft battery in their yard.
