Roger is a down-to-earth builder, Judy is the harassed single mother of four teenage boys, and Thelma is a librarian who usually looks as though she's been sitting on a wasps' nest for most of her life. Neville is on the lookout for a woman (any woman will do), and Julian just wants to be young again. Edie is the wrong side of 70, and Roz is a size zero fitness queen. These characters, together with one very overweight Alice, all meet up for the first time at their local Pilates class. Petra, the class instructor, has no idea what she has let herself in for!
