When paramedics 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 so sure: she remembers the raw terror in his eyes. Detective Ella Marconi shares Jane's doubts, which are only compounded when the case becomes increasingly tangled. The victim's boss tries to commit suicide when being questioned, a witness flees their attempt to interview her, and then to confuse matters further, a woman is beaten unconscious in front of Jane's house and Alex's daughter goes missing.
