What starts out as a voyage to the West in pursuit of the American Dream quickly turns deadly for the Donner party after a series of bad decisions and severe weather.

Punishing storms trapped the party with nearly no food or shelter for 5 months in the Sierra Nevada mountains. Many died, some succumbed to cannibalism to survive, and others delved deeply into their faith while waiting to be rescued. “The Donner Party” explores this exciting journey through a hybrid of first-person narration, remarkable reenactments, expert interviews, CGI, and archival materials.
