The premise is that Henry Willows, a 40-something who has been divorced from his wife for seven years and is perfectly happy living alone in London until his oldest child, Matthew arrives to live with him after being thrown out by his mother. The episodes generally revolve around Henry's annoyance at having his solitude disturbed and the age gap between father and son. Henry employs two cleaners during the show's life; first Enid Thompson and in the third series, Fiona Fennell.
John Thaw as Henry Willows - Henry is a divorced middle-aged man who lives by himself, but when his son, Matthew, turns up on his door step, expecting to be waited on hand and foot, his life is turned upside down.
Reece Dinsdale as Matthew Willows - Matthew is a teenager who gets himself into trouble, and is obsessed with girls and money.
Elizabeth Bennett as Enid Thompson - Enid is Henry's first cleaner. She is nosey and appears to be attracted to Henry.
Joan Blackham as Fiona Fennell - Fiona is Henry's second cleaner.
Rebecca Lacey as Julie Willows - Julie is Henry's daughter and Matthew's sister. Despite living with her mother after her parents' divorce she appears to be a daddy's girl.
Sheila Hancock - Sue Willows - Henry's ex-wife. She only appears in one episode. Hancock is the real-life wife (widow as of 2002) of Thaw.
The US version, You Again? was less successful and lasted two seasons, totalling 26 episodes. Elizabeth Bennett reprised the role of Enid in the show.
The Dutch version, Ha, die Pa! (Hello, Dad!) ran from 1990 to 1993 and was broadcast by NCRV. Luc Lutz (1924-2001) and his son Joris starred as Norbert and Matthijs Hoogendijk. Keeping it in the family, Pieter Lutz (1927-2009) guested as the homeless old man in the adaptation of the 'Getting on?!' episode. Matthijs' sister Freddie was played by Bettina Berger.
