Collision

DI John Tolin returns to work after an extended period of leave, but his first case back is a doozy: a multi-vehicle accident involving police officers, the car they were pursuing, a millionaire businessman, and a mysteriously abandoned van.

In the aftermath of the crash, the policemen assist Gareth and Alice in the car they had tried to pull over. Daniel Rampton flees the scene in a panic, while businessman Richard Reeves bonds with service-station worker Jane as he’s treated for injuries. Inspector Ann Stallwood takes control of the case, and later at the hospital, Karen Donnelly is frantic to retrieve the documents from her car.

Daniel Rampton has been on the run since the accident, but he contacts his brother for help. With her mother in critical condition, Christine questions how her husband, Brian, walked away from the crash unscathed. Meanwhile, Tolin investigates the disappearance of Karen Donnelly and clashes with Stallwood over the case and their own unresolved personal issues.

After Jeffrey and Sandra are brought in for questioning about the body found in Daniel’s van, Sandra demands that her husband come clean to her and takes charge of the situation. As Tolin digs deeper into the mystery of Karen’s killing, he begins to uncover a corporate conspiracy, even as he endures an emotional crisis with his daughter.

Tolin searches for another copy of the files that Karen stole from her company. Stallwood finally determines what caused the crash that impacted all these people’s lives.
