When railway owner Kingsley puts his daughter Helen in charge of a section of his line, she discovers that the previous manager had been a pawn of Roberts, Kingsley's general manager. Unknown to Kingsley, Roberts has been using the line to advance the interests of his own fruit packing company over that of a smaller competitor, Jack Stewart. Helen and Jack soon join forces against Roberts. In a fight between Roberts' and Jack's men, Jack's side gains the upper hand, until one of Roberts' men throws a block of ice at Jack that knocks him down and sends the freight car on which he is standing careening down the track. Helen saves Jack and the freight by chasing it down on another car, lassoing the freight and stopping it before it crashes. In a later confrontation, Helen is able to jump free before a terrible crash occurs between a trolley and the freight that Roberts is manning.—AFI
