Based on characters created by Earl Derr Biggers. We recognize the characters from other Chan movies. In this movie Warner Oland gets to play the notable Charlie Chan.
This movie has a big surprise with the cast of actors for just a standard Chan production. We get to hear Boris Karloff sing and prove that he can act in roles other than Frankenstein's monster. Keye Luke plays Lee sone of Chan. Keye Luke looks quite different as Master Po in the Kung Fu TV series.
A noisy singing amnesiac sees a paper that jogged his mind. Now with his memory back it is reeving time. Can Charlie figure it out before there is no one left in the opera house?
