Following a chance encounter with a young history student, Lance and Andy embark on a journey towards the discovery of a lifetime. All they need to do is get permission from the local landowner, the mad one who is rumoured to have done away with his wife.

Lance and Andy haven't told anyone that they are hot on the trail of the holy grail of metal detecting - the final resting place of King Sexred of the East Saxons. But members of the rival detecting club already seem to know all about it. Who is the mole?

Andy spots something suspicious and Sophie's cracking on with her new friend at the library. The club is visited by the local mayor on a matter of some delicacy, and some old enemies seem unusually interested in Peter's quest to find his grandfather.

Just as they're losing their farm, Lance and Andy start finding good stuff. But old enemies are sniffing around. Home lives are chaotic as usual and Lance is persuaded to try hypnotherapy for an awkward affliction. With mixed results.

Terry announces that he is standing down as leader of the DMDC, unleashing a bitter winner-takes-all scramble for presidential power when Andy and Lance fall out over gold. Becky and Sophie are forced to become allies in the Two Brewers pub quiz. Is this Andy's worst idea ever?

Andy's been thinking about internet dating. Not for him, but for his friend Lance who's still not over the departure of his ex-wife. A mysterious stranger arrives to tempt the Danebury Metal Detecting Club in more ways than one.

Andy suddenly has a job interview to go to, while Lance has a lot of catching up to do. The mystery of the buried bomber is the least of their problems, but a disturbing possibility emerges from an unlikely source that throws everything into doubt.

Lance's flat isn't his own any more and Andy's staying with the mother-in-law. But at least they have their old faithful permission to escape. Or do they? The dark cloud of a solar farm threatens the tranquillity.

With time running out, Andy and Lance go to great (action-packed) lengths to protect their land. Away from the fields, life is no less stressful as Andy quits his job and Lance finds an unwelcome guest in the spare room. An audacious theft leaves Lance reeling.

Russell and Hugh embark on their mission to recover the mayor's chain of office from the car park in Barnfather Woods, while Sophie proves she's still very bad at spying. Both Becky and Lance have something important to tell Andy.

After recent revelations, Lance, Andy, Becky and Sophie are all trying to come to terms with an uncertain future. In fact, only one of them is going to get a good night's sleep when Terry puts his emergency plan into action.

Lance is obsessed with finding the thief that stole his gold, which means he can ignore the melodrama going on at home. Andy's lies are catching up with him too. They decide camping out is the safest option.

Club president Terry is keen to help Lance and Andy search the bottom paddock at Bishop's Farm, but only because he's convinced that's where Larry Bishop has buried his missing wife. Meanwhile, Lance is determined to get his ex along to hear him play at the local pub's folk music night.

Even though Andy, Lance, Becky and Sophie are barely talking to each other, their secrets are on the verge of being revealed. Are they all just victims of a smear campaign? And why does everyone else want to move in on Bishop's Farm?

A huge hole has been excavated and police are looking into it. Meanwhile, Larry Bishop's invisible dogs have disappeared without trace, and Andy and Lance now have one last chance to discover their hearts' true desire.

Andy and Lance become eco-warriors when they find their beloved oak tree is due to be felled. But a 24hr helpline turns out to be more of a hindrance. Andy stumbles upon treasure when for once, he wasn't even looking.

Finally, it is the day of the DMDC's annual rally and Terry is expecting a really big turn-out. But for Andy and Lance, will the day bring heartbreak or triumph?

“There's something about karma going on” is Lance's wise observation, and there certainly seems to be something in the air. They have one last day on the farm, one last chance to pull out all the stops and find that gold. Terry's got a new gazebo. Perfect time for a rally.
