Tech entrepreneur Craig's latest invention - a dating app for bird lovers called 'Wingers' - has failed, bankrupting him in the process. He has no choice but to relocate to his personal idea of hell, a self-sustaining eco-community in mid-Wales called People's Haven run by his estranged big sister and "massive weirdo", Sunlight (real name Tracey).

For Sunlight, Craig's arrival couldn't come at a worse time. Not only does she hate him with every fibre of her being, but tonight is the monthly Joy celebration, a unique take on the harvest festival, where Sunlight gives a notorious (or if you ask her, "beloved") performance. Can Craig and Sunlight deal with their difficult history, or are they about to make each other's lives much, much worse?
