Trying to be impressive, the friends tell Luisa they are headed on a road trip to a beautiful, secret beach called Boca del Cielo. Intrigued with their story and desperate to escape, Luisa asks if she can join them on their trip. Soon the three are headed out of Mexico City, making their way toward the fictional destination. Along the way, seduction, argument and the contrast of the trio against the harsh realities of the surrounding poverty ensue.
