Madge looks like a perfectly respectable woman in her late 60s, albeit one who lives life to the full. She has a loving relationship with former magistrate Eric and is firm friends with Eric's daughter Sam. She is a member of a health club and takes regular - if not entirely successful - trips to Zumba. But behind this reputable exterior, Madge is hiding a very big secret. She has a husband called Mike who has been in prison for the last 12 years. Since she met Eric, she has hidden behind yet another lie - claiming she volunteers at the prison. But the truth is bubbling under the surface and is about to spill over the edges.
