1957. A catastrophe occurs at the pharmaceutical lab in Coventry where sixteen-year-old Wilf is working for the summer. A catastrophe that needs to be covered up at all costs.

2017. Phiney is shocked by the death of her grandfather, Wilf, who has jumped from a railway bridge at a Coventry station. Journalist Mat Torrington is the only witness.

Left with a swarm of unanswered questions, Phiney, Mat and Wilf's wife, Dora, begin their own enquiries into Wilf's death. It is soon clear that these two events, sixty years apart, are connected - and that Wilf is not the only casualty.

But what is the link? And can they find out before any more lives are lost?
