蓝衣Photon solar energy group is aiming to build a solar farm in Danebury. Blissfully unaware of the plan Andy and Lance are still looking for buried treasure - construction worker Andy, with Becky and their baby living with disapproving mother-in-law Veronica whilst Lance is sharing his flat with his messy, noisy teen-aged daughter Kate. The group is shocked to read of Photon's intention in the local paper - but then Andy makes a potentially interesting discovery.
