The world is changing fast in the fading frontier town of Penwyllt, and no-one knows this more than its unlikely heroes Margaret and Clive, who, like the other folk of the town, are plodding their way through life, with routines they’ve grown used to, full of faces they know and people they trust.

It was an accident, right? A terrible accident. Margaret never meant to hurt Glyn - or did she? After all, does the subconscious ever lie? Will Margaret and Clive stay and face the truth or will they run?

Ruth Ellis is called to the forest to investigate Glyn's torched truck, but there's no sign of Glyn anywhere. How long will Margaret and Clive be able to keep their secret?

The cracks are stating to show, with Glyn still missing and Ruth‘s line of questioning pushing ever closer to the answers. How long will Margaret and Clive be able to hide?

It’s one thing concealing a crime if you’re a couple, but when three people know the truth, it’s a ticking time bomb. Is blood thicker than water? Can Sylvia ever forgive Margaret?

With Clive safety back in the fold, Margaret and Sylvia can breathe a huge sigh of relief, but for how long? Because Clive has come home with a plan - he wants to give Glyn a proper burial.
