Tim's (Leslie Fenton) girlfriend Alice disappears mysteriously. Tim heads to New York to ask his amateur detective friend Clay (William Powell) for help. Clay and Tim go to the theatre, Tim recognises the star as Alice but she vanishes again! As Clay tries to unravel why Alice has vanishes again, a number of murders take place indicating that there is a criminal connection. Clay is helped throughout by the perky Donna (Ginger Rogers).
A complicated plot though much of Clay's amateur sleuthing seems to consist of low level bickering with Donna and moving from one sumptuous Art Deco room to the other.
This is a great fun film though the plot can be a little hard to follow at times. Powell and Rogers work well together.
