"In a Welsh community that has been left behind, a large construction project offers hope for a better future. But an explosion, followed by a catastrophic collapse, leaves many dead, children included, and the community devastated."


That's the concept behind The Accident, Jack Thorne's new four-part drama starring Sarah Lancashire.

Here are the cast and characters you need to meet...
