Some months ago, Leo Bannister walked out on his wife and daughter. Now, he is in a relationship with Liz, a girl half his age who feels under appreciated and wants marriage. But what does Leo really want?
Leo proposes marriage to Liz but their engagement does not promise to be a happy one what with Liz's mother not approving of Leo and Leo not approving of Liz's youthful friends.
Liz moves out after a row with Leo but can't seem to find anywhere to stay. After a row with Shirley and her mother, and a pitiful attempt at seduction by the mousy Colin she returns home to her uncertain fiance.
Liz is bored at home alone so she acquires a dog. Meanwhile, Leo's older daughter breaks up with her newly out of the closet husband, so Leo is forced to tell his daughters about his relationship with Liz.
Alice threatens to commit suicide so Leo rushes over to see her which causes a rift between Liz and him. Torn between two women, he reaches a decision: "I must empty my life".
