As a nit pandemic sweeps the school, Julia stands accused of triggering a second wave, so she throws a nit treatment party that brings all the drama (and headlice) to her door.

The mums (and dad) join the merry go round of secondary school open days as they face the choice of where to send their kids at 11. Julia panics about which catchment area she lives in and even considers a fake religious conversion to beat the system. As Kevin's divorce progresses, Liz helps him navigate the shark pool of lawyers and makes a worrying discovery about her own situation along the way. Meanwhile, queen bee Amanda struggles with playing second fiddle to Meg's illness.

Mother's Day leaves Julia feeling ignored while Meg gets spoilt rotten. Amanda endures a passive aggressive lunch with her appalling mother Felicity, played by Joanna Lumley.

Julia, Liz and Meg endure the school coach trip from hell with their nemesis Ashley (Martha Howe Douglas) while Kevin helps Amanda pack up her shop with unimaginable consequences.

At the PTA charity FUNraiser, Julia resolves to leave Paul for her builder Garry, Kev's attempts to clear the air with Amanda backfire, and Anne finally loses her rag.
