In the sun-drenched streets of Tijuana, young Karla, a seemingly innocent teenager, finds herself in a world of taboo desires. Alone in her room, she explores her body, her fingers dancing over her moist, virgin lips. Her heart races as she imagines the forbidden fruits of the city outside. Suddenly, a knock at the door interrupts her secret pleasure. It's her older, visiting cousin, who's been watching her from afar. He's a man of the world, and Karla's naivete excites him. He offers to show her the city's darker side, starting with a lesson in the art of pleasure.
