PE teacher Tony Mammoth is back from the dead with his old job back. He's determined he'll approach it the same way as in the 1970s, including parents' evening. Along the way, he finds out he has a lot more in common with a pupil's mum than he thought.

Reeling from some recent news that drops a bombshell on his life, Tony Mammoth tries to make up for lost time. But despite his best efforts, things don't go to plan, and he and Theo end up in a fight with a stranger. Meanwhile, his boss, Lucy, has to fight off the local oddballs looking to donate to help her fertility treatment.

Following the passing of his old friend - and pub landlord - Barry, Mammoth decides it's time to find someone special to spend the rest of his life with. He soon finds out that it's hard to date in the modern world, so he has to quickly learn the contemporary dos and don'ts. He soon hits it off with someone but manages to blow it in pure Tony Mammoth style - dead rabbit and all.
