In CRACKS IN THE RAINBOW, Rick Dover, an LAPD homicide detective, receives an urgent call from his partner, wanting to meet late at night. On the way, Stretch dies in a flaming car wreck. After the shock wears off, Dover examines the circumstances, becoming suspicious of the "accident." But only he and his new partner, Falcon, think the matter should be investigated.

Using maxims from Stretch, chess psychology, nuclear physics, knowledge of movie lore, and street savvy, Dover and Falcon uncover a covert group of cops, feds, and military, connected by the FBI's computer, plotting to launch ethnic cleansing in America. Only Dover can stop them, if they don't kill him first.
