In the pulsating heart of an Argentine discotheque, cousins Esperanza and Fernando find themselves drawn together, their bodies swaying to the rhythm, their eyes locked. As the night wears on, they slip away from the crowd, their hands entwined, leading each other to a dimly lit corner. Fernando's hand finds Esperanza's thigh, slowly inching upwards, as she leans in, her breath hitching, and whispers, "We shouldn't..." before their lips meet in a hungry, desperate kiss.
