Set in the 19th century, the plot follows the adventures of two orphaned Irish siblings (Tom and Mary) who emigrate to the United States to reunite with their uncle Niall in New York City.

[1][2][3] When Niall doesn't show up at the docks, Tom and Mary set out to find him with the company of a stray dog, Sparky, sneaking on board a train with a group of orphans when they cannot afford a ticket.

The children have a close call with a pack of coyotes that leaves Tom with an injured leg, and when they stop to collect water they are captured by an Indian tribe.

The two groups work together to stage an assault and rescue the prisoners before the bandits can destroy the now-depleted mine to cover up their actions.

[16] Javier Ocaña of Cinemanía rated the film 3 out of 5 stars, considering that, while "soft and ultimately relying too much on chance" vis-à-vis the outcome of the story, it is "entertaining, and it has "some nice gags" and an "excellent pace".
