Rig 45: Murder at Sea
9pm, More4
The Swedish thriller continues to make good use of the self-contained environment of the oil rig to unspool its murder mystery. After the shocking events of season one, Petra faces prison. However, she claims fresh evidence can be obtained if she returns, in police custody, to the rig. This doesn’t go down well with the riggers – but a hard drive is discovered and Benthos Oil seems furtive in response. This series occasionally stretches plausibility, but it’s involving generic fare. Phil Harrison
