One crew - one killer. Andrea (Catherine Walker), a damage regulator from Benthos Oil, is sent out to Rig 45 two days before Christmas to investigate a fatal accident. When starting to investigate, Andrea finds that the crew of the rig is unwilling to talk to her and she has a hard time finding out the truth. Just when the rig is hit by a hurricane and all forms of communication to the mainland is cut off, the crew realize that the accident is in fact a murder, and they now know that they are in real danger. With a murderer amongst them, questions are being asked - who is the killer?

This series is a spin-off from the long running BBC medical drama "Casualty". Set in the same hospital as its sister series, this show follows the everyday lives, professional and personal, of the doctors, nurses and patients who find themselves, for various reasons, in the wards of Holby City General Hospital.

Amanda Burton plays Helen West, a crusading senior prosecutor with the Crown Prosecution Service. Helen's life is complicated by her ongoing affair with a senior police officer (Connor Mullan). This miniseries of three episodes was based on the novels of Frances Fyfield.
