The Tequila Mockingbird (a statue rather like the Maltese Falcon) has been recovered by Esmerelda, a CONTROL operative posing as a cantina showgirl in a sleepy Mexican town called Mira Loma. KAOS kills Esmerelda during her performance but she has hidden the statue beforehand. Max (undercover as a down-and-out doctor) and 99 (undercover as a Spanish singer, who performs "Cielito Lindo" as part of her act) have to figure out the clue that was left behind to find where the statue is hidden, leading to a mexican standoff between Max and two rival KAOS agents.
