The detectorists join forces with the freedivers to find not one but two family heirlooms lost by a heartbroken daughter. Glass artist Peter turns old thrown away bottles into stained-glass beauty, and archaeologist Sam looks into what could be our oldest find by our youngest treasure hunter.

The scuba team take on a search for a son's precious last gift from his late father... but with a vast search area will they be successful? Elsewhere, the freedivers and detectorists head to the natural pools at Buttermere for a clean-up and are surprised to find something of great value.
