When the Broker Brothers - two serial killers - kidnap Sam, she realizes that Danny isn't who she thought he was. When Sam falls in love with one of the brothers, she fathoms just how many risks she is taking. Will Sam escape the brothers and win love or will she just be another body added to the body count?
