Movie Coverage

Contrived, crazy, not very believable, but people do crazy shit so it's remotely possible. Man dies of a heart attack and leaves the key to a bunker to his daughter. She locates and opens the bunker and finds a man down there. He's wearing an iron collar with a length of chain attached. Now, what do you do with a case like this? Any normal person would call the police, but she is from a wealthy family with a position in society. Word of this gets out and the scandal could destroy them. So she's in a bit of a dilemma.

How did we get here? The prisoner tells her a fine story. Your father got drunk, gets in his car and hits a person on deserted rural road and kills him. Loads the body in the trunk of the car and drives down a dirt road into the woods and buries him. The prisoner, his friend, is with him during all this. Guy knocks his friend in the head and locks him in a bunker on the family estate. Keeps him there for 30 years until he dies. 

The father was a big wheel. How did he manage to keep his visits to the bunker secret? He must have been a devil to get away with this for so long. I've heard other stories* about people who have been secretly imprisoned for years, but they were either loners or their families were in on it. 

* Also Korean movie Oldboy from 2003.
