They're not metal detectors, they're metal detectorists! Odd couple Lance and Andy forge their friendship in muddy fields away from their own dysfunctional lives. Mackenzie Crook writes, directs and stars as Andy – a wannabe archaeologist who, alongside his friend Lance, spends his time in muddy fields with a metal detector and a packed lunch, dreaming of finding that priceless Saxon hoard that will make them rich and cement their place in detecting history. But as they go off on their adventures, real life keeps getting in the way. They embark on a journey of greed, betrayal, rejection and redemption as they hurtle towards Danbury Metal Detecting Club’s greatest ever find.
