Abby and Martha Brewster are two nice ladies who put lonely gentlemen out of their misery with poisoned elderberry wine. Mortimer, their nephew, is a theater critic who hates theater. His brother, Teddy, thinks he’s Theodore Roosevelt. Another brother, Jonathan, is a murderous thug on the run who looks like Boris Karloff. Throw in a minister’s daughter, a plastic surgeon and a cop who thinks he’s a playwright and the result is laughter and lots of it.
