The ensemble includes Singh (Avi Nash), an Indian-American socialist prisoner who repeatedly voices critiques of capitalist exploitation, collective action, and the prison system while quoting Eugene V. Debs; Anna (Julia Jones), an Indigenous woman who joins the crew after escaping a boarding school with the historical slogan 'Kill the Indian, save the man' and shares her resistance to assimilation; and tensions between the racist Rankin (Austin Amelio) and others that layer class and racial allegory onto the group's dynamics.

These elements appear in dialogue, backstories, and subplots as the crew treks with the gold, framing the prisoners and Anna as victims of unjust systems. The premise remains a tense heist-adventure driven by Murphy's desire to reunite with his daughter, with the ideological threads functioning as period-flavored character texture rather than the core emotional or narrative engine.
