The teenage son of Conrad and Ellie Cain, a wealthy New York City family, has been kidnapped - and everyone, it seems, is a suspect. Desperate to find their son, they hire an expert named Knapp, a man known for his high-profile (and particularly dangerous) rescues. With Knapp on board, the Cains try to stay under the radar of local law enforcement while dealing with the kidnappers and growing distrust of each other.
