Serenity Plaza is the most exclusive gated community in South Wales. You’d kill to live there. Jack and Ianto have gone undercover as a happily married couple. There are rumours that something’s wrong at Serenity Plaza and they’re determined to investigate. But the problem is that Serenity Plaza is just so rigidly normal. Suddenly, Jack and Ianto have to confront the problems that normal couples face. Sharing a house together, doing the washing up, entering the residents’ baking contest, and hoping to win the Best Kept Lawn. Competition is fierce. Because this is Serenity Plaza. And you’d kill to live there.
