Showman Pel Pelham (who works contracting sleazy acts for a freakshow carnival) is contacted by an old friend Tony who has received a blackmail letter signed "Delores". Pel agrees to check her out as she lives near a friend of his. Reaching her apartment, he discovers she is an old pal of his named Rena Meroni, who has fallen on hard times and got mixed up with someone she regrets. She agrees to withdraw her blackmail attempt, as it was not her idea.
In the apartment downstairs Pel offers to set up his Russian friend, Sapolio, in a freakshow "starvation act" in a glass cage to break the world record. A party is hastily arranged for that night for their carnival pals. In the evening, Sapolio sees a man going up to Rena's room. During the party Rena is found murdered. The chief suspect is Tony because his blackmail letter was discovered near her body.
Unsavoury character Rorke first attempts to blackmail Stanton, who he knows had a motive; and then also Tony, but the latter draws a gun and in a struggle it is Tony who is killed. Rorke tries to frighten Pel by kidnapping his wife, but she escapes and the police arrest Rorke. Pel tries to get Sapolio to remember who he saw on the night of Rena's murder while he was "starving" in a glass cage. Someone passes strychnine-laced food inside the cage and Sapolio, suffering from the poisoning, breaks the glass and accidentally kills himself. His death is covered up by Pel and the police to tempt the poisoner to come back to finish the job. He falls for the trick and returns only to be confronted by police and shot dead while trying to escape.
