While Amneris prays at the Temple of Isis, Aida ventures to the banks of the Nile, where Radamès has arranged to meet her. She first reminisces about her distant homeland and is then joined by her father, who, through a mix of flattery and threats, persuades her to find out the location of the Egyptian army from Radamès. When Radamès arrives, Aida convinces him to flee with her using a safe route without any fear of discovery. Unaware of the deception, he reveals it to her. Amonasro rejoices, and Amneris, emerging from the temple, discovers everything. Aida and her father escape, while Radamès surrenders himself to the guards.
