Dan presents Emma with a perfect vision of a family and embarks on a journey to rediscover a terrible truth about a misremembered friendship.

Dan is frustrated by the universal lack of respect for his new status as a father, and decides to join a local dads' club. Desperate to fit in, how far will 'Papa Bear' go to impress the other dads? Brian is worried about his daughter's cultural identity, and Jo adds to his stress with her box of 'things I don't understand'.

Dan takes his Behavioural Unit on a historical school trip with desperate hopes of becoming a 'bright light' his troubled kids can follow.

Dan can't believe his luck when a health visitor suggests a 'daddy day'. But when his son seems a bit cold towards him, Dan becomes increasingly desperate to establish a bond.

Dan races against the clock to prove his credentials as a dad, but a terrifying figure from his past surfaces to seek revenge.
