There was this one movie I watched as a kid which I think started with a scene with these 2 kids, or teens, a girl, and a boy, who were walking along a dock and the girl broke through the dock near the edge of this water body, i think it was a lake. She screamed for the boy to get help, and when he ran to get help, I think he got hit by a car at the end of the scene, i think it was the first scene in the movie or show. From my memory, the scene was in colour and looked to be released during the late 2000s or early 2010s.
