DCI Ellis and assistant DS Harper arrive in the town of Callorwell to investigate the disappearance of a local detective, Jenny Rawler. The missing person's colleagues believe she left of her own free will, but Ellis and Jenny's husband feel something is amiss.
DCI Ellis, a tenacious cop, is parachuted into failing investigations alongside her partner DS Harper. Each case will bring her to a different police station where she'll have to not only immerse herself in the case, but also win over the local police.
