Choke (2001)

Henry, an uptight businessman who sometimes acts with questionable ethics, nevertheless rejects Ron, a scam artist who wants a partner. Ron won't let up and finds a lever to blackmail Henry, whose daughter Gina has killed a pedestrian in a hit-and-run car accident. To protect Gina, Henry disposes of Ron, but a murderous sociopath witnesses this crime. Henry and this stranger bond in an odd way, telling stories about their childhoods. Henry makes a deal with the stranger, helping to get rid of the body of one of the stranger's victims. Will this act seal a bargain between the two men and get Henry off the hook, or will the stranger threaten Henry and Gina?
