Popular British film starlet Betta St. John essays a dual role as Toni and Terry Trent, twin entertainers hired to perform for the USO in Britain. After witnessing a murder, Terry abruptly vanishes, whereupon Toni asks Peter Brady to locate her missing sister. It is up to Brady to pull out his patented invisibility tricks to fool the gangsters holding Terry captive--but there's more to the intrigue than meets the eye (or in this case, doesn't meet the eye).
