Cleaner (2008)

Retired policeman Tom Cutler (Samuel L. Jackson) works as a crime-scene cleaner to support his young daughter. Cutler's quiet life is thrown into turmoil when woman-in-peril Ann Norcut (Eva Mendes) contacts him in the wake of a routine job. When Norcut reveals that her husband has disappeared -- and that his agency has sterilized an apparent crime scene in her home without her permission -- Cutler turns to his hardened former partner, police Detective Eddie Lorenzo (Ed Harris), for answers.
