Mexico's new president vows to attack the drug trade; in retaliation, his wife has already been assassinated. Carlos Bravo is a secret service agent: he's fired when the son of the president reports that Carlos has spent the night with the president's daughter. Carlos joins a Mariachi band to stay close to the president's ranch in Morelos. He's performing at the ranch when a drug lord invades with the help of the president's son, takes the president, his daughter, and many visiting dignitaries hostage, and demands the return of a huge shipment of cocaine that the government has confiscated. Carlos slips away from the hostages and begins a one-man rescue effort.
