The film was co-written by West from her play Frisco Kate, which she wrote in 1921 and a story written by the duo Marion Morgan and George Brendan Dowell.
Sister Annie is on her way to rescue a financially troubled mission in Nome, and inspires Rose, but dies en route.
Rose assumes the identity of Sister Annie to avoid arrest, dressing her as a prostitute in a scene later deleted by the censors.
The Frisco Doll decides to keep Sister Annie's promise of rescuing the mission and raises the money by combining soul-shaking sermon and song with street smarts.
She's romanced both by a beautiful young Sheriff being generally investigative, and the blustering, slightly crazy ship's captain, Bull Brackett.
Acknowledging his view as a minority opinion, Greene noted that his interpretation of West's characterization of Salvationism to have been harmless fun and not as a satire on religion.
