Three young Dinopaws and their parents recount the story of Gwen, Bob and Tony on one dark cold night and their quest to find light and warmth. Gwen is certain that she saw something shine in the sky, but no one else saw it. Bob and Tony follow Gwen, collecting many other Dinopaws on the way, but every time they crest another hill, the thing that shone seems even further away and it's getting colder and darker. They all squeeze into a cave to shelter. Once inside they discover that being together keeps them warm and makes them happy. Togetherness will get them through this darkest winter - the gang break into song and are filled with love and inner light. Gwen found the thing that shone - it was within them all along.
