After a childhood spat drove brothers Wilder (Arliss Howard) and Wallace (Dennis Quaid) apart, they went their separate ways, until a chance meeting brought them back together again. Gifted with a psychic ability to spark fires, Wallace supresses his gift, marries the lovely Vida (Debra Winger), and attempts to lead a normal life. However, he runs into his brother, who is using his powers to work as a carnival attraction, and their reunion leads to disaster when the brothers begin to compete for Vida's attention.
