An unexpected wartime bomb hits Ducketts Passage and blows Gary and his son into to the present. Yvonne returns early from Switzerland, her holistic cosmetics business becoming increasingly successful, and Gary has to explain away the lad's existence when they bump into each other at Ron's. Meanwhile, Gary & Phoebe consider moving to Mayfair, which should be safer, and find they have a famous neighbor.

Gary is moving up the social ladder in both eras, though not smoothly in either. Noël Coward helps Phoebe to cope with living in the West End when she has trouble with the butcher, by showing her how to improve her accent. As Yvonne's business makes her a celebrity, she plans a new house, and is invited to the Woman of the Year awards, which is followed by a party at No 10 Downing Street. Gary and Phoebe get their revenge on the butcher.

Ron signs up with a dating agency. Yvonne makes a date with Gary, but when an unexploded bomb goes off in Ducketts Passage he has a problem. It is so serious that Ron misses his date to come to help. The two sides of Gary's life collide head on, and it appears that now others can travel between the 1940s and the 1990s.

Ron takes advantage of the new ability to use the time gate, and as Gary's supposed commanding officer can do anything he wants. Since Reg has been promoted to a position in Scotland Yard, Ron takes everyone to a West End club to celebrate, but becomes a huge liability for Gary. Unfortunately, Yvonne obtains complimentary tickets to a Chelsea soccer match for the very same evening.

When Gary runs short of money, he decides he must break his own rules to get out of trouble, and starts betting on the horses. Phoebe is distraught, as her father was a gambler, and repeatedly tries to dissuade him.

Yvonne continues to travel for Nature Boy Cosmetics. Gary takes Phoebe to the Cafe Royal, where his false wartime identity finally catches up on him, and he is recruited for a secret mission to the Isle of Wight. However, Yvonne also has a special mission for him. When he arrives at his destination in 1943, the Isle of Wight looks remarkably like France.

Gary realises that he is only being used as a ploy to fool the Germans. As the Gestapo closes in on him, he is captured and is to be sent to Berlin for torture, unless he can escape first. Ron stands in for Gary on an errand for Yvonne: meeting a top model, and escorting her to a product launch - but they get sidetracked.

Gary is very unsettled after his French adventure, and he feels like he's losing his mind: he can't tell whether he's awake or asleep, dreaming or experiencing reality. Then Rolf Harris appears in one of his dreams...

Yvonne is signing copies of her just published autobiography. Meanwhile, Gary finds out from the porter in the 1990s that the owner of his 1940s West End flat is going to be killed in a road accident - what is he to do? He finds a new occupier. Then, racked with guilt, he decides to cause a happier ending.

Phoebe wants to make a career of singing, and she wants Gary to write a new song for her. When he does, he has no idea what he's started. Ron wants Gary to help him with a personal ad. A visitor to the shop surprises Gary when he realises it's his son. Gary wants to go back and change the future for Michael for the better.
