A young girls body is dumped, horrifically mutilated and drained of blood. Her death is an ominous mirror image of an unsolved 1940s case in Los Angeles known as "The Black Dahlia". Detective Constable Anna Travis must race against time to catch this copycat killer, dubbed "The Red Dahlia" from the flower his victim wore in her hair. But there are no suspects and a media frenzy is spiralling out of control.
