"Arsen & Spitzenhäubchen"

A cozy, somewhat outdated house in Brooklyn in the 1940s: This is where the two lovely old ladies Abby and Martha Brewster live. Surrounded by their nephews Teddy and the theater critic Mortimer as well as their lovely neighbors, they lead a relaxed and quiet life.
But the tide turns one day when the shocked Mortimer discovers the body of an elderly man in the window chest. At the same time, his hated sister Joanna turns up at the Brewsters' house with a certain Dr. Einstein.
Mortimer's nerves are now completely frayed. Where did this poor old man's body come from and how can he get rid of his psychopathic sister as quickly as possible? To make matters worse, a bunch of police officers who are friends of his aunts turn up at the house. And his fiancée Elaine just won't leave him alone...
