Mickey (Ray Liotta) recounts the cross-country journey of his 15-year-old self (Trevor Morgan) and his young brother, Roger (Rory Culkin), who suffers from muscular dystrophy, to see baseball player Roberto Clemente's 3,000th hit. Their mother (Lauren Holly) doesn't know where they went, so the cops track down the "stolen" car as they travel to Pittsburgh. Determined to see their idol's historic event, the boys will do anything to get to the baseball stadium, including hitch a ride on a train.
