Living with his daughter, Susan, and her new partner, Victoria, is taking its toll on Gerald. Victoria turns out to be a bathroom hogger and Gerald is therefore forced to make use of the facilities at work.

Gerald and the Health and Safety team are under pressure from the Mayor of Baselricky to prove that playing conkers is dangerous enough to warrant safety measures. Meanwhile, Susan pushes Gerald to invite his ex-wife Valerie over to start repairing the family rift.

There is a toilet roll thief at large at Baselricky Town Hall, distracting Gerald and his Health and Safety team from a vital investigation into the safety of playground swings.

Gerald clashes with the Mayor in his fervour to author his own iconic hazard warning. Sue is threatened with industrial action and Victoria's DJ career stalls.

Gerald and his team decide that kerbs are dangerous trip hazards, while Sue sees another side of her mum's new boyfriend.

Tensions run high for the Big Ballroom Night and, while investigating the size of takeaway coffee cups, Gerald and his health and safety team uncover a startling conspiracy.
