"Speedo: A Demolition Derby Love Story" profiles demolition-derby driver Ed "Speedo" Jager, who's as passionate about his two sons as he is about driving. In fact, he has remained in an empty marriage for years for their sake. During the film, a third love enters Speedo's life: Liz Mallows, a New Jersey track official who's drawn to his in-your-face (in-your-fender, actually) energy and his take-no-prisoners driving style. "It's like a disease," Speedo says. "It starts to possess you when you're really into it."
