New York City
In this farcical and macabre comedy, Mortimer is about to get married when he discovers his two, sweet spinster aunts are homicidal maniacs who take in lonely old men and poison them. They are assisted by Mortimer’s mentally-challenged brother who believes he is Teddy Roosevelt building the Panama Canal in the basement. To make matters worse, Mortimer’s murderous brother also shows up looking like horror-film actor Boris Karloff after having plastic surgery. As Mortimer realizes that insanity might run in his family, he must deal with his family, the Brooklyn police, his fiancé and a dead body!
