BlackJack: Ace Point Game (2006)

After wearing a wire to catch a dirty colleague selling confiscated drugs, detective Jack Kempson is hated by his colleagues. He also gets 'promoted away' to the basement, where old files get transferred to the national computer database. Thus he comes across fingerprints, now identifiable, in the 30 year old case of Ashley, the kidnapped son of lottery winners. Although he's too late to help him now, he tracks the perpetrators down behind his boss's back.
