Thirty‑two‑year‑old Alice has a middle‑class marriage that others envy. Her husband Richard is a senior bank executive who provides abundant material comforts, yet their marriage is frigid. Plagued by Richard’s physical issues, their relationship is little more than a hollow formality, leaving Alice trapped inside a gilded cage. Richard’s younger brother Noah comes to spend the summer, and their old romance resurfaces. They had been lovers before Alice’s marriage. Back then, Alice’s father fell seriously ill. Richard forced Alice into marriage by offering to cover her father’s medical expenses, and the two were torn apart.
