Detectorists

BBC Two, 9pm

Metal-detecting enthusiasts Andy (Mackenzie Crook) and Lance (Toby Jones) are back for a full-length one-off special, five years on from series three.

The series three finale saw the pair finally get their break as they find their stolen gold (albeit from a slightly less intimidating thief than expected). Despite striking gold, Andy and Lance are back riffling through bushes and mud with their metal detectors as it’s revealed The Danebury Metal Detecting Club is in danger of losing their beloved scout hall after losing out on a big finder’s fee.

When a mysterious relic is found, Lance makes a decision that puts his friendship with Andy and the future of the DMDC in danger.
