I can remember prett much everything except any of the actors and the title.
So this guy is poor and he receives a phone call while he's in this car, telling him to kill some fly that's in his car and he'll get like $100 or something. He does it, Then the voice from the phone tells him to eat it for a different amount of money, more than the first time.
This continues. Always a phone call. Even if he throws away his phone it finds a way. Eventually he ends up going to an apartment and finding a dead body. He then has to take the dead body to a cafe, and it must have a cup of black coffee in front of it by a certain time. Cops come in, are a little suspicious, but the cafe waitress is slow so the guy steals one of the cops' coffees and places it in front of the dead man just in time,
2 other people are also receiving the same calls, and he is in a race with them to see who finishes first to win the million.
there is someone who is tracking him, and has been tracking other contestants in the game. he lives in a trailer.
Near the end, in order to win the million, he must kill someone.
He goes to kill his father. It turns out his retarded brother was the other contestant, and he has gone to kill the father as well.
the father knows this because he had played the game too.
