One cold November night, police detective Martin Preuss joins a frantic search for a seven-year-old girl with epilepsy who has disappeared from the streets of his suburban Detroit community. Unwilling to let go after the Oakland County Sheriff's Office takes the case from his city agency, he strikes out on his own, following leads across the entire metropolitan region.
Probing deep into the anguished lives of all those who came into contact with the missing girl, Preuss must summon all his skills and resources to solve the many crimes of love he uncovers.
