The new specials pick up some time after the original series left off and reveal Jean Hardcastle's (Dame Judi Dench) great anticipation for grandchildren, much to husband Lionel's (Geoffrey Palmer) dismay.
Jean has cots delivered to the house in the hope that Judith and Sandy will soon be having babies. Lionel explains that they may not want children. He dreams of looking after babies that multiply at an alarming rate.
Alistair and Judith collect Sandy and Harry from the airport. Back at Jean's house, an emotional Sandy tells Jean Harry wants to kill himself. Harry, meanwhile, explains to the others how he plans to join the armed response unit to gain a promotion. Jean wants him to be talked out of it, but Sandy insists it must be his decision.
Alistair begins to behave peculiarly and Judith fears it is because she has been unable to get pregnant. She knows she is healthy and concerned the problem lies with Alistair. Jean offers Lionel's services to talk to Alistair, but Lionel refuses to be drawn into discussing such personal matters. However, when Jean connives to leave him alone with Alistair, he finds himself suggesting seeking medical help.
