Mexican bolero singing sensation, Ramon Ponce, finds his overnight success as an international recording artist threatened by a stalking fan at the end of his concert tour in San Antonio, TX. Intent on defending himself from an attack, he contacts local gringo, firearm instructor, Ricky Johnson, to train him in last minute self-defense tactics. Removing their hats and sunshades at the shooting range, they discover an uncanny resemblance to one another. Offered a hefty price to switch places, the Texan agrees to appear on stage as the singer's double, not expecting a devious scandal and paparazzi heyday to follow a PR trap he falls victim to, hours before the concert. Determined to save Ramon's public reputation, the Texas gunman learns the price of fame and success, at the expense of true love, living the singer's life for twenty-four hours and discovering the secrets behind the broken-hearted love songs he writes for the woman of his dreams. Inspired to save his own failing marriage, Ricky plots to win back the heart of his wife with an English version of Ramon's latest, unreleased bolero, held in his possession as guarantee of payment for surviving the singer's final performance.
