Lindsay vows to protect a twenty-year-old victim long enough to see her 21st birthday. SFPD Sergeant Lindsay Boxer has sworn to defend against all enemies, foreign and domestic. As Lindsay prepares to celebrate her own daughter's birthday, she clashes with rising Chief Charlie Clapper over a family case. When a distraught mother pleads with Chronicle reporter Cindy Thomas to investigate the disappearance of her daughter, Linda, and baby granddaughter, Lorrie, Cindy immediately loops in SFPD. But Linda's schoolteacher husband, Lucas Burke, tells a conflicting story that paints Linda as a wayward wife, not a missing person. If what Lucas tells law enforcement has even a grain of truth, there isn't a woman in the state of California who's safe from the reach of such an unspeakable threat.
