As a nit pandemic sweeps the school, Julia finds herself accused of triggering a second wave. Ostracised by the other Mums, Julia needs to find a way back into their good books so she throws a nit treatment party that brings everyone's drama (and headlice) into her home.

The party reveals that Anne has some big news, Meg is facing a crisis, and Kevin has committed a terrible crime of passion. As Amanda super spreads the gossip, Liz waits for news about a career move.

It's Mother's Day in Motherland and Julia is feeling completely ignored, while Meg's family have gone way over the top in reaction to her cancer diagnosis.

Anne is beside herself with excitement at the prospect of a day out with her Mammy, while Liz and Kevin try to avoid Mum stuff altogether with a trip to the countryside that becomes an impromptu driving lesson for Kev.

Meanwhile, Amanda's mother Felicity travels from Cheltenham for a gloriously passive-aggressive celebratory lunch.
