If every married couple in America could see "Welcome Home," there'd be no divorces in 1926.

Fred Prouty and his wife, Nettie, are living happily until the day that his aged father shows up on their doorstep. He immediately begins creating havoc, upsetting the once-orderly household and trying to force his opinions on everyone. Nettie does her best to be patient with the old man, but the day comes when he brings a group of his pals over while she is holding a meeting of a fashionable club.
