When counterfeit money is found in circulation around Royal Oak, Ron tells Gary that the Germans flooded England with forged notes, leading Gary, Reg, and Phoebe to attempt to catch a Nazi spy. Meanwhile, back in 1996, Ron and Stella's marriage problems are continuing to escalate.

Gary is on top of the world, but pride comes before a fall, or in Gary's case, several falls. Meanwhile, after taking some seemingly sound advice from Gary, Ron's marriage hits an all-time low.

Much to Yvonne's dismay Ron unexpectedly turns up at the Sparrow household with suitcase in hand, Stella has thrown him out and he needs a place to stay. Meanwhile, back in 1942 Phoebe's orphaned niece and nephew Sally and Peter return from Buckinghamshire to move in with her at the Royal Oak.
