Watch LookMovie. Based on the true story of Jim Baker, a former insurance salesman from West Mifflin, Pa., known for having the Immaculate Reception ball in his possession for several decades. On Dec. 23, 1972, Baker and his then-14-year-old nephew attended the AFC Divisional Playoff game at Three Rivers Stadium between the Pittsburgh Steelers and Oakland Raiders. With 22 seconds remaining and the Steelers trailing 7–6, Steelers fullback Franco Harris scooped a deflected Terry Bradshaw pass out of midair just inches from the turf and ran it into the end zone for an improbable, game-winning touchdown.
