Orphan Hilda Swanson's prayers are answered when a Swedish-American colonization company agrees to send her to America. Aboard the steamer, she meets Olaf, a young Swede, and Donna, an enemy courier who is posing as a passenger. Learning that the secret service is on her trail, Donna sews secret documents into the hem of Hilda's skirt. She then sends a wire to her comrade Felix Martinez, notifying him to intercept the Swedish girl. Hilda and Olaf innocently evade Martinez and are sent West by representatives of the colonization company. Missing their train at a stopover in cattle country, they are taken in by Larry O'Keefe, a big-hearted rancher. Martinez finally tracks them down and arranges to have Hilda kidnapped by some Mexican cattle thieves who take the girl to their hut, only to discover that she no longer possesses the papers but has given them to O'Keefe. Hilda escapes and meets Larry who has been searching for her. Meanwhile, Donna, unaware that she is being trailed by secret service agents, arrives at the O'Keefe ranch. The agents arrest both Martinez and Donna, and as Hilda hands over the papers, the agents assure the Swedish girl that she has done a great service for her new country. Larry then offers to marry Hilda, thus making her an official American citizen.
