Dave Tolliver, tower signalman on a mountain railroad, takes in his relief man, Joe Standish, as a boarder. During a storm, Standish becomes drunk and makes advances to Dave's wife, Sally. Although warned of his wife's predicament by his son, Dave is compelled to stay on the job when a runaway freight endangers a passenger train. He ditches the runaway and saves the express, while Sally successfully defends herself by shooting Standish.
