Dreams die in sheds in Suburban Hell, traded for garden decorations so the neighbours can see how well everyone conforms. Matthew was a popstar, once. His band went on and made it without him, so now every night he goes to the shed to jerk off over his keytar, the one Karen wants him to give up so that she can get higher-tier garden decorations. But too much semen could break his beloved instrument, so Matthew builds Sparky, a robot that takes his cum. One night, Sparky comes to life, but soon discovers he has no voice. And why would he? Matthew built him to swallow spunk, not to speak. Left in the shed after he serves his purpose, Sparky sets out on a journey to find a voice. Along the way he meets Sandy, a robot like him, only Sandy is powered by a different man, an evil man. Together, Sparky and Sandy scour every inch of their neighbourhood, breaking into nearby garden sheds, exposing the neighbours, all in search of a voice for Sparky the Spunky Robot.
