A solicitor comes to tell Rigsby that an uncle has left him fifty thousand pounds - on condition he can prove he is married. Since Rigsby parted from his actual wife Veronica years ago and she moved away, he persuades Ruth to pose as his 'wife' when the uncle's widow, Aunt Maud, comes to check on his marital status. To confuse matters the real Veronica also shows up but, since he does have a wife, he is allowed to inherit the money. Unfortunately it is all eaten up by his uncle's unpaid taxes.
