Living with his grandmother and burdened with guilt, Mark vows to find the hit-and-run driver and take his revenge. The only detail he remembers is round taillights swerving in front of his family's car, and he's shocked when he notices the car of the high school's bully, Jeff Marino, has identical taillights-and a suspicious dent.
Now he wants revenge more than ever...
Jeff believes Mark is an anti-Vietnam War activist like his cousin Gary-and despises him for it. To make matters worse, when Jeff's girlfriend Genie Lombardi dumps him for Mark, it kicks Jeff's hatred for him to a dangerous new level.
Lies and threats escalate, until drugs and a shocking death send Jeff over the edge, and his campaign to get Genie back any way he can turns violent.
When Mark's memory begins to return, it leads to a terrifying confrontation.
Will he finally prove the identity of the guilty driver? Or will he and Genie become one more tragedy associated with the Carquinez Bridge?
