In Bar (movie, 2007)

A group of young high society friends, aged between 18 and 25, are gathered at a friend's bar that they regularly frequent for the night. But when they finish of their last beer and prepare to head home they find themselves held captive at gunpoint by five strangers. With their mouths, hands and feet tied, they are tortured, raped and murdered until the next morning. The gang who have captured them have no clear reason, they just want to punish these young people for everything left incomplete in their lives.
