The Keeper (2004)

In Redwood County, the dancer Gina is attacked and her boyfriend is killed by a maniac in a motel. Gina is attended by Sergeant Burns and Lieutenant Krebs insists in giving a lift to her when she leaves the hospital. However, he kidnaps Gina and arrests her in a cell in the basement of his isolated house. The deranged policeman has a serious trauma from his childhood with dancers of night-clubs and establishes rules and punctuations for Gina while she is imprisoned. Meanwhile, Lieutenant Krebs is stalked by a local, Ruthie, who has a crush on him and wants to promote his amateurish puppet show with the character Deputy Rock, his alter-ego. Sgt. Burns is trying to find a clue where the missing Gina may be.
