The large scar on the trainer's leg and the presence of a mysterious spider distract Mara and she is disqualified. While walking sadly on the beach, he hears the screams of a woman drowning. Without hesitation, he swims towards her and is surprised when he arrives, because there is nothing but water. The sudden visit of Inés - her mother's sister - means for Mara a discomfort that will become unbearable. But the news of her acceptance into Laura Martínez's team keeps her excited.
