Don Cesar de Echague, masquerading as the avenger "El Coyote", continues the American troops' fight against injustice and perversion of justice against the Hispanic population of California in the mid-1840s. At the same time, he courts the charming Leonor de Acevedo as a nobleman who lives inconspicuously. She rejects him at first because she only knows him as a cowardly nobleman, but rewards him with her love when she learns about his true calling.
