What do you get when you mix music, dancing, comedy, and spies? This entertaining concoction for one, starring Eleanor Powell as a tap dancer working on an ocean liner heading for Puerto Rico who is unknowingly recruited by spies to smuggle secret plans. Bert Lahr, Red Skelton, (an uncredited) Frank Sinatra, and Tommy Dorsey and His Orchestra (with Buddy Rich) also star. Songs include "Poor You" and "On Moonlight Bay." 96 min. Standard; Soundtrack: English.
