Plot Summary

Sam Abbott helps his parents pack their family wagon as they prepare for the arduous journey from Missouri to the Oregon Territory on the Oregon Trail. While Sam is busy packing and worrying about the journey ahead, he loses sight of his younger sister, Amelia.

In the modern-day US, Ranger, an intelligent but distractible golden retriever, is playing in his yard with his owner, Luke. Ranger is intrigued when he discovers a metal First Aid box in the garden, and he’s frightened when that box transports him through time to pioneer-era Independence, Missouri.

Ranger is overwhelmed by the strange, busy town but understands that Sam and his mother are looking for Amelia. Determined to help, Ranger catches Amelia’s scent from her doll and tracks her down while Sam follows him. Sam meets Sarah Ferguson, a young girl and fellow pioneer whose family is traveling in the same wagon group as Sam’s. When the Abbott family leaves, they invite Ranger to go with them. Though he wants to be reunited with Luke, he decides to stay with the Abbotts and try to protect the children.

The family begins the journey, facing long uncomfortable days of travel in difficult terrain. As the days pass, they reach rough, sandy terrain. When a stampede of buffalo approaches, Ranger warns the family in time, allowing them to make a wagon circle and protect themselves from the herd. Pa Abbott and his friends shoot at the buffalo, scaring off the herd and killing one buffalo, which they skin and eat. The family is grateful to Ranger for warning them.

Sarah reveals that her parents are sick, and Dr. Loring confirms that they have cholera. The Ferguson parents die during the night, and the Abbott family must quickly bury them and move on. The group is thrilled to reach Independence Rock, an important milestone on their trip. The kids use gunpowder and bacon grease to write their names on the rock, just like the pioneers who passed through before them.

Sam is excited to explore Independence Rock with Ranger. As he climbs, Ranger warns him of a rattlesnake nearby, and the Abbott family rewards Ranger for his help. The Abbott family arrives in Fort Bridger, where they find Sarah’s Uncle Aaron, who has arrived to take her home with him. Ranger is sad to say goodbye to Sarah but happy that she’s safe with her own family. The Abbotts continue to travel westward and reach the mountains, where it snows overnight. Sam feels nervous about their next stop, Three Island Crossing.

The Abbott family prepare for the Three Island Crossing, a treacherous river crossing over the Snake River. While Ma Abbott, Ranger, and the children are safely ferried across by Shoshone men, Pa Abbott faces the dangerous task of driving the livestock across the river on horseback. Ranger and the family watch Pa get swept off his horse and into the water. Ranger takes action and finds the rope in the family’s wagon. Ranger uses the rope to swim out to Pa Abbott. Sam Abbott pulls in his father and Ranger. The whole family is relieved and thankful for Pa’s survival, but things take a turn for the worse when Sam feels ill.

Sam contracts mountain fever and sleeps in the wagon while the family journeys on. He eventually recovers, and the family is delighted to finally reach Oregon, where their Uncle Thomas is waiting to take them to the farm. Ranger notices his First Aid box humming and says goodbye to Sam. In the final chapter, “Home,” Ranger is transported back to his backyard, where he joyfully reunites with his owner Luke.
