Cold earth (2008)

When a celebrity couple's daughter goes missing, everyone -- including the police -- believes a serial killer is the culprit. The truth, however, is not so cut-and-dried. With no clues or ransom note, detectives must look to old demons for answers. Alex Walker plays Alex Blight, a paparazzo whose knowledge and connections raise suspicions, and Steven Elliot and Ben Shockley play the detectives assigned to the case in this taught thriller.
