Jonny is in a real pickle: he wants to split up with his 43-year-old girlfriend/boss, Liz played by Leslie Vickerage, but is too scared to do so. Adam, meanwhile, is happy to keep teasing him about her age ('I'll switch the stair lift on'). Grandma, played by Frances Cuka offers Jonny some advice - 'Take her out dancing' - before showing him how to dance in the kitchen. While they dance to the music on the radio, it transpires that it's just the music for the news headlines, and before long, Jonny and Grandma are actually dancing to the news. Adam is loving it. Meanwhile, Dad has been drying fish under the stairs (Dad: 'Have you never had dried fish before?' 'Not from a cupboard' replies Adam). Then Grandma gets locked in the boot of Adam's car, and everything changes. How will they get her out? And as if that isn't bad enough, Jonny's girlfriend, Liz turns up at the house.
