On a warm suburban night, the sound of lawn sprinklers is drowned out by the rumble of hot rods. Suddenly, a car careens onto a family's neat front yard, teenage boys spill out brandishing chains and leather, and a young man cries out for the girl he loves. Tonight, fathers will pick up snow shovels and rakes to defend their turf, and children will witness a battle fuelled by fierce, true love. This is the night they will talk about and remember as the moment things changed for ever.
