In the shadow of the Hollywood sign on the outskirts of Los Angeles are the city's roughest neighborhoods. In the late 1990s, LAPD's Foothill Homicide Unit investigated hundreds of murders, but only Detective Lindy Gligorijevic was dubbed "the killer closer". Driven by the need to give her victims a voice, Detective Gligorijevic revisits her most shocking cases with the Foothill Homicide Unit. Detailing how she solved each crime, and revealing how she convinced the most cold-blooded killers to confess, Detective Gligorijevic knows she can't bring closure to someone who's lost a loved one to murder, but she'll stop at nothing to get them justice.
