Alma is deaf-mute from birth. Together with her sister and her friends, she runs her family business, a hostel in Argentine Patagonia where one of her main attractions is taking tourists diving in the submerged forest. Diving is her greatest passion and the depths of the lake her world. The possibility of having a cochlear implant puts her in the dilemma of choosing between listening for the first time in her life or diving again in the depth of the lake.
An unexpected diagnosis forces a group of friends to rethink their life priorities.
