A pond-side alarm opens the episode when Mia is pulled from the water after a fall while a visitor brings koi. Present are Mia, Natalia, and their grandmother; the doctor reports Mia was rescued in time and is not in mortal danger but is shaken. Family reactions split: the grandmother downplays the incident and someone says, "I need to take advantage of this." Suspicion rapidly hardens into accusation—witnesses insist Natalia pushed Mia—leaving Natalia isolated and the household facing the accusation unresolved.
