Mary's brother Lewis is flying in from California. He is a successful businessman and single.
Mary plans to set Lewis up for a date with Rose. Mary thinks Rose would be right for him, se is homely and the kind of woman that Mary would want as a sister in law.
It is not long before maneater Sandra gets her claws on Lewis. She has an eye on a successful wealthy man.
Meanwhile Mary and Rose fall out. The date did not go that well. Rose thought Lewis was all about talking about himself and nothing else. She thinks that Mary is welcome to have Sandra as a sister in law.
A predictable plot but surprisingly funny. Straight from Lewis turning up with a tiny swimsuit for Brenda, which in itself is a tad icky.
