Rick and his crew must launch a rapid refurbishment when the Pawn Stars steer a 1950s Atomic Missile pedal car to the shop. Can they follow the tough trajectory of this hazardous heat-seeker, or will this mission miss its mark? And later, a client brings in a 1930s fare box, once used on public transportation. Can the crew keep this transformation on track, or will this ride-on restoration go off the rails?
