A suburban family copes with the death of their teenage son, a well-liked varsity athlete who excelled in school. He and a passenger were killed when his car ran off the road and hit a tree. As the family piece their lives together, trying to move on, they start finding things that indicate he may have had a second life - and been involved in criminal activity. The passenger in his car was a girl, but she wasn't his girlfriend - she was someone no-one had seen before, and she wasn't carrying ID. Someone keeps calling the son's cell phone and hanging up. His computer is locked down with sophisticated encryption software. The last straw is that when his mom is cleaning his room, she finds a gun in a box under his bed. At this point, the parents can't be in denial any longer. They have to decide whether they'll go to the police, ruining their son's good name, or keep it a secret and hope nothing comes of it. They decide to tell no one. I'll let you take it from there.
