The Deputy (1970)

Part-time Deputy Toby Sawyer is jolted awake by Chief Krueger and assigned to guard a dead body until the coroner arrives. When the corpse mysteriously vanishes, Toby launches a frantic search and unwittingly discovers decades of wrongdoing…and several cops who have turned a blind eye, including Deputy Billy Banks, who pressures Toby to ignore his findings. Only Deputy Amanda Jackson appears trustworthy. Desperate to keep his job, Toby must unravel the town’s deep web of corruption before he and his career end up as dead as the missing cadaver.
