A young mother and her child are ruthlessly gunned down while returning to their car in the garage of a shopping mall. There are no witnesses, and Detective Lindsay Boxer is left with only one shred of evidence: a cryptic message scrawled across the windshield in lipstick. The same night, the wife of A-list actor Marcus Dowling walks in on a cat burglar who is about to steal millions of dollars worth of precious jewels. In just seconds there is an empty safe, a lifeless body, and another mystery. Before Lindsay and her friends can piece together either case, one of the killers forces Lindsay to put her own life on the line - but is it enough to save the city?
