Betty and Herbert have been together since their late teens. They share everything — a home, a life, a cat, the remote... Well, almost everything. You see, Betty and Herbert don't really 'do it' anymore. Their status is permanently set to coitus interruptus. How are you supposed to be up for a saucy spanking when ten minutes ago you were arguing about who's putting out the rubbish? But, after a surprisingly pleasurable weekend of spontaneous sex, Betty and Herbert start to wonder what they've been missing. Are they in danger of throwing their relationship on the sexual scrapheap? Drastic action is needed so Betty sets a challenge: they must spend a whole year seducing each other, taking it in turns to come up with a steamy new scenario each week. Funny, moving, and occasionally gymnastic, this is the story of how one couple lost their inhibitions, reignited their desire and got their groove back.
