A strange discovery on a roundabout prompts Michael to convert his garden shed into an alchemist's laboratory and attempt to generate homunculi from the recipe in his dad's old journal. But his neighbour Clive is getting suspicious and starts to sniff around.

Kacey invites Michael to the pub, where they drink too much and he reveals to his workmates much more than he should about his mysterious experiment. Meanwhile, back at Marvin Gardens, something strange is starting to happen in the shed.

The prophets have to be buried in horse manure to make them grow, and Clive is at the end of his tether when a truckload of the stuff is dumped at the front of Michael's house. But Bev is intrigued and wants to be involved.

On the way back from work, Michael narrowly avoids being robbed when the would-be assailant mistakes him for someone else. When Kacey comes round to help bury the jars and asks Michael about the boxes hoarded in his house, he opens up about Clea and the life he once dreamed of.
