Matthew could have been big. His band went on Top of the Pops, after he left. Years later and Matthew is filled with regret. Matthew's keytar lives in the shed in his back garden, along with a robot he built himself. Every night, he wakes up with bloated balls to relieve in the robot. The cum brings Sparky to life. Matthew forgot to equip Sparky with a voice. Every shed in the neighbourhood conceals lost dreams, as Sparky discovers when he searches for a voice. Every time a part of the resident dies, they are rewarded by the unofficial neighbourhood association with permission to buy more garden decorations. Sparky meets another cum-powered robot in a shed. Together, they can save or destroy suburbia, depending on which robot is answering the questions. Matthew is at the end of his tether. His wife sucks, only not him. His job is awful. His former band have an army of menopausal fans to pay into their crowd sourcing campaigns. He wants everything he gave up when Karen became pregnant all those years ago. She wants to sell his keytar at a car boot sale so she can have more garden decorations.
