Wealthy aunt Cassandra (Sarah Padden) sees off an attempt by her relatives to have her declared mentally incompetent so they can get their hands on her cash. She invites them to spend the night at her isolated country house. When one of them is murdered, radio reporter Bob White (Wallace Ford) comes in to investigate.
More murders take place in a house riddled by hidden passages and tunnels. One of the relatives is suspected to be the culprit (though the field is gradually being narrowed down), while Bob and his assistant Nora (Marian Marsh) are struggling to work out what is going on amid all the nonsense and red herrings, Aunt Cassandra has a cunning plan...
This is objectively not a good film, it is a bit too chaotic and many of the actors mill around without much to do (and not doing that well). However, i loved it! It is a fun film, the goofiness makes it hard to take seriously as a crime drama, but if it is approached with an open mind then it certainly is entertaining.
