Crossing is a vividly human re-imagining of the love, sacrifices, and history that laid tracks for the North America of today. Leaving behind ancestral Chinese homelands and their family, brothers Yang and Lee face harrowing challenges as they join countless immigrants seeking a better life in the 1860s. This story follows their remarkable journey across the ocean to San Francisco, then into the Sierra Nevada Mountains, where they'll labor to build the Transcontinental Railroad. Surrounded by California's new marvels, and carrying their cultural traditions in their hearts, Yang and Lee find themselves in precarious situations. Their passions, struggles, dreams, and bravery create ripple effects for generations. Locations: Panyu District China and California; camps at Newcastle, Auburn, Colfax, Cape Horn, Dutch Flat, Alta, Cisco, Donner Summit, Donner Summit Tunnel #6, and Coburn's Station (Truckee).
