I watched a video around the mid 80's, it was about a pretty girlfriend, and mistrusting boyfriend. The boyfriend hired a private I to follow the girlfriend, she was very faithful to him till this one time she was on a trip, had a flat and a tall nice looking hitchhiker fixed her tire, and she had a one night stand, the hitchhiker went by the name of Trey or Tray,
It turns out he private I had issues, he was the bad guy killer, in the scene he kills the boyfriend with a shot muffled by a pillow, the scene showed feathers floating around.
He then tries to kill the girl and Trey saves the day, of course the gets shot, but he is wearing a necklace and the bullet hits it and he is not killed and saves the girl. Trey was nice looking, didn't say a lot, long to med. Hair. Does anyone remember this movie?
