Andy is preparing to commit suicide when he is disturbed by a call from his sister Sam, begging for help with child care. Andy and his nephew Errol are reluctantly thrown together for the day.

Having been moved on whilst busking, Andy's day goes from bad to worse when he calls round to Gwen's flat and meets her new boyfriend, Casper; and Sam has a meeting with Errol's Dad, Ben to discuss custody.

Sam is mortified when Errol catches her in an embarrassing position; meanwhile, Andy is horrified when Val Pearson catches him spying outside his club. Andy holds auditions for his new band so he can enter Battle of the Bands.

Errol's paternal grandmother is hosting a family lunch and Sam ropes Andy into coming along for moral support. Unfortunately it's just as Errol's `cool' uncle Rex arrives home on holiday and Andy embarks on a competition to win Errol's affections.

While Sam attempts to attract a cool new sponsor and Errol is away on a school trip, Andy tries to break up with Shelly, make up with Gwen and woo Errol's teacher Melodie, but can Andy really juggle three women at the same time?

Andy and Errol are offered the opportunity of a lifetime: to sign with Rage Records and infamous music producer, Mo Kahn. Little does Andy know Mo's only interested in the kid and Errol hasn't worked out how to break the bad news.
