Dick Benton, a young attorney of the railroad, is on his way to the Capitol to deliver evidence involving Riggs in a conspiracy arising out of a fight with the railroad over a franchise. At Lone Point he learns that by leaving the package to be picked up by the express it will reach the Governor sooner than he can bring it on the local. He leaves it in Helen's care. But Riggs, who has been following Benton, succeeds in getting away with the box and boarding an auto standing outside the station. He has scarcely gone a hundred feet when a momentary loss of control causes the car to ram a telegraph pole. Helen recovers the box, but looks up to find another automobile with Riggs' aides bearing down upon her. While they are tending the injured Riggs she boards an electric speeder, a development of the handcar, and races down the track. In a moment the conspirators are after her. Suddenly the express swings around the curve, on the adjoining track. Ahead, Helen sees the switch which will send her to almost certain death under the wheels of the express unless her speeder is brought to a stop. She tries frantically to apply the brakes, but they will not work, and in a twinkling she is at the switch and under the express. By a matter of inches she escapes the wheels of the train and races along the other track apace with the express above her. When she has finally mastered the brake she calls to the trainmen above her, and both express and speeder are brought to a stop together. The trainmen quickly effect the capture of Riggs and his fellows.
