When paramedic Jane and Alex encounter a man refusing to get out of his crashed car, with bystanders saying he deliberately drove into a pole, it looks like a desperate cry for help. His frantic claim that someone is out to get him adds to their thinking that he is delusional.
Later that day he is found dead under a train in what might be a suicide but Jane is no longer sure: she remembers the raw terror in his eyes.
Detective Ella Marconi shares Jane’s doubts, which are only becoming increasingly tangled. Then, just when she thinks she is closing in on the right person, a shocking turn of events puts more people in danger and might just see the killer slip through her hands.
