Wren Linton must protect her father's theater from her brother. She travels to the Republican era via an antique pocket watch, kissing Young Marshal Vaughn Fulton. Vaughn is a Wusheng performer of Wren's ancestral Lin Family Opera Troupe. Wren learns opera from Vaughn, and uses his identity to find her lost pocket watch. Wren sees Vaughn as a tool, but he falls for her, and she reciprocates. Wren faces a choice: stay for love, or return to protect the theater.
