Gary and Phoebe's wedding is drawing near, but will Gary's stamina hold out for two stag nights, 54 years apart?

Gary and Phoebe visit wartime Liverpool, where Gary meets his hero grandfather, Albert. However things become very complicated when Gary is forced to play hero.

With a wife on both sides of the time warp, Gary is rapidly running out of money and Ron has lost the will to print.

The pressure is definitely mounting for Gary now that both Yvonne and Phoebe are pregnant. Yvonne is trying to get him a job in her firm so that she can give up work after the birth. Meanwhile, in 1942 Gary is accused of being a fence.

Ron is in trouble with the police, while Phoebe tells Gary that they are finally free to marry.

Yvonne leaves her job and Gary struggles to revisit 1942, where Phoebe is wedding planning.

Gary oversleeps and misses his 1942 wedding. While In the present, Yvonne is upset that he's forgotten their first anniversary. Back in 1942, Gary appeases Phoebe and the wedding goes ahead.

Yvonne is out of town so Gary hopes to spend some time with Phoebe, but Gary's father George turns up and stuns him when telling a story about discovering a time warp in his youth.

Yvonne has a miscarriage and Reg's mistress leaves her husband, who mistakes Gary for Reg.

Yvonne's new health drink is about to go into production, but Gary is primarily concerned with Phoebe, who is going through childbirth back in the 1940s.

Both Yvonne and Phoebe are pregnant and feeling unwell. Yet Yvonne and Gary agree to babysit Gary's nephew, Arthur, who goes missing during his visit and is suspected of having time travelled to 1942. So Gary might not be the only one that can access the time portal after all.
