Andrew is caught in the middle of a dispute between Peggy and Richard. Trying to take her mind off the argument, Andrew asks Peggy to look after a colleague's budgerigar.

In an effort to reconcile Peggy with her long-distant sister Marjorie, Andrew invites his aunt to stay. He soon finds out why the sisters don't get on, and why having Marjorie in the house is such a bad idea.

Peggy embarks on a programme of good deeds. But when she takes on more than she can handle, there is only one person to whom she can turn for help - her son, Andrew.
