Paula Sen is a teenage swimmer of immense ambition. She knows that her coach won’t praise her for coming fourth. She has a recurrent dream: she is swimming smoothly through the air, pushing off from the walls of buildings, her arms sweeping through the ether. She looks in the mirror of the great swimming champions, although she wants to surpass them, not become their equal. She doesn’t know where her ambition comes from, but she wants to see what she is capable of. She plans to break a world record, excel in all four strokes, and even invent her own, Sen stroke. She is desperate for a gold medal, to climb onto the top of the podium, but she doesn’t want to come down from there until history remembers her as the greatest legend ever found at a swimming pool. However, such a demanding sporting life, between megalomania and neurosis, brings personal costs, which she will experience in the heat of competition.
