I remember seeing a film on TV in the early 1980’s. I was about a man in a pickup truck who sees a UFO and his vehicle stops and he gets out and finds a glowing rock which he puts in his toolbox or lunchbox. I think the glowing rock gave him strength I think, but it burnt people when they touched it. I think there was a scene when his son finds the toolbox/ lunchbox and nearly touches the rock. The main character’s job is something to do with oil or gas or something in a refinery I think. It was in colour and set in America. It might have been a TV movie. I guess the film might have been made late 1970’s.
