Warrior Season 3 keeps painting a harrowing picture of San Francisco's history. It continues the journey of Ah Sahm (Andrew Koji) in the late 1800s, as he helps lead the Hop Wei Tong. Unfortunately, there's a rising white nationalist movement, with Mayor Buckley using the Asian faction as pawns. Leary is also trying to get them killed so that more jobs would come the way of the Irish.
