Red Light is like a waking dream on the streets of Los Angeles. It is the story of a woman's transformation into her true self and her friends' wild chase after the woman they think they have lost. Rachel is considered a fool by her friends, but everything changes when a chance encounter turns into sex so hot it lasts all day and all night. Driving home one evening, Rachel's roommate spots her car without her and assumes the worst: Rachel has been killed by the handsome man behind the wheel. By going looking for her, she unwittingly sets in motion a series of events. We watch as all of her friends join the hunt and, one by one, they find themselves in their own little dreams, driving through the lonely streets of Los Angeles and meeting lovers who take them to the heights of ecstasy.
