"1000 Tons of Steel! 200 Lives at Stake! 100 Miles per Hour! One Man to Stop it!" The action takes place on board the Grand Royale, a luxury train controlled by a supercomputer created by a shady electronics firm called American Rail. Inevitably, human error causes the computer to suffer a glitch -- and as a result, the Grand Royle speeds precariously out of control. It is up to hero Glen "Lucky" Singer (Robert Urich) to stop the train and rescue the human cargo!
