Exploring Larry Bishop's land Lance and Andy find nothing of interest though they do encounter Art and Paul from the rival Antiquisearchers, whom they send packing. Bishop tells them that some years ago he found some treasures which he gave to Justine but declines to say who Justine is. He also gives them some gold but they decide to keep it a secret. Actually Sophie has heard what they are doing but believes from her research that the Saxon hoard they want is in the next county. Lance meanwhile is anxious to reform his old folk duo with Andy so that he can perform a song he wrote at the open mike pub night in the hopes of winning back ex-wife Maggie from her younger new boyfriend Tony.

Andy and Lance perform at the open mike evening but Lance is upset that Maggie does not come to support him whilst Andy's insistence that his girlfriend Becky should not turn up to see him looking foolish leads to her believing he is having an affair with Sophie. They decide to tell Terry that they have permission to dig up Larry Bishop's land and, as an ex-policeman still determined to catch Larry for the suspected murder of his wife, he is happy to join them. Unfortunately the result is rather explosive.

Still puzzled as to why she left him Andy visits Becky, who shows him the incriminating photo. He does make it up with Lance, who confesses to Sophie that he has won over a quarter of a million pounds on the lottery. He does not tell her that Maggie has asked him for a loan to save her shop. Sophie is however seen to be a traitor when it transpires that she is a former member of the Antiquisearchers and with the army declaring Larry's farm a free-for-all the group considers disbanding though Terry saves the day by withdrawing his resignation. Andy discovers that Becky is pregnant but there is a more disturbing discovery - human remains found on the farm, supposedly those of the late Mrs Bishop, with Larry being charged with her murder.

Lance learns that Maggie has known about his lottery win whilst Andy wins back Becky by selling his detecting equipment and promising to give up his activity. In the pub they meet Larry Bishop, who tells them that his wife is alive and well and the bones dug up belonged to his dead dogs. The club holds an open day but the only person to turn up is Sophie, who informs everybody that Antiquisearchers have been disqualified from the dig for placing nails on the site. Becky's excellent local history knowledge comes in very handy as everybody rallies to find the Saxon hoard and whilst they fail to unearth it there is reconciliation all round.

A slightly jealous Andy spies on Sophie as she helps Peter with his research and on Lance as he secretly meets Internet date Kate though Lance and Andy unite to warn rival detectorists Simon and Garfunkel against joining the search for the plane wreckage. Becky meanwhile, bored with her job, considers voluntary work abroad and the mayor asks Terry to help him find his lost ceremonial chain.

Charged with finding the mayor's lost chain detectorists Russell and Hugh are disturbed to find themselves in a dogging area but since the mayor owns the field with the plane wreckage in it they are told to keep searching. Andy is less than enthusiastic when Becky tells him that she has put them both forward for voluntary work in Africa but he gets an even bigger surprise when Lance tells him the identity of the young lady with whom he has been seen.

Andy passes his interview but keeps the fact a secret from Becky, which so annoys her she considers leaving him, whilst Lance is worried that his overly effusive actions have lost Kate forever. The pair discover that Peter is an impostor whose real interest is in unearthing a cache of gold coins in collusion with Simon and Garfunkel and without a licence to do so. A nocturnal stake-out results in Simon and Garfunkel being arrested though Peter escapes.

Despite interruptions from curious ramblers Lance and Andy are finding more and more Roman coins. However Lance's sea-sickness leads him to see hypnotherapist Dr Hoffman so he can stay on girlfriend Toni's houseboat - though its success is questionable. Meanwhile rival detectorists Art and Paul have made their own arrangement with Photon, which Lance needs to challenge.

After Lance and Andy have raced Art and Paul to what they believe is a Roman burial site Andy quits his job when the boss destroys a Roman mosaic at the site. Unfortunately he fails to tell Becky when they go flat-hunting. Lance is jubilant at finding a gold coin but he is not happy when a magpie flies off with it - and Maggie, on her own again, decides to return to him when he is hoping to have Toni stay at his flat.

As Lance and Andy determine to save an oak tree in their field Kate puts in a good word for her father with Toni, with positive results. Andy is also pleased to discover a run-down cottage he feels he and Becky can afford to buy at auction and, in his efforts to save the tree, inadvertently comes upon the answer to his problems, despite the efforts of Art and Paul with the Bat Action Trust .

As Kate moves onto Toni's houseboat allowing Toni to move in with her father, Lance and Andy call a truce with Art and Paul, allowing them to excavate the potentially valuable field. Thanks to Veronica, Andy and Becky can buy the cottage but the pursuit of treasure still proves to be elusive to the group.

With the scout hall suffering from lack of funding, Andy and Lance have the perfect way to raise funds with their new dig. But why does Lance want to keep it a secret from everybody?
