Ken throws an OAP party at the Community Centre. Ivy tells Elsie that the girls want to play a joke on Mike and need her help. Mavis is depressed over losing the house and Derek. Hilda turns up for the factory Christmas party dressed as Charlie Chaplin after Bet tells her that it's fancy dress. Mike is annoyed when Suzie invites a lad, Robin Smethurst, to the party. Both he and Steve are furious at her cheek. Ivy, Elsie and Vera play their joke - complaining about their small bonuses before descending on Mike with mistletoe. Mavis helps out at the OAP party. Gail tries to lure Steve away from the factory party but he's too occupied by Suzie and Robin. The comic booked for the OAPs doesn't turn up so Mavis recites poetry to them.
