Synopsis：After five years of marriage, Sophia wakes from a car accident to a cruel truth: her husband Daniel has been having a long-term affair with her younger sister, Casey. She fakes amnesia to test them, and Daniel, desperate to cut ties, lies that she is actually married to her older sister, Taylor. Smitten with Sophia at first sight, Taylor plays along and slowly seduces her—from daring kisses to passionate nights—until Sophia completely falls. When Casey pushes Sophia into a pool in front of everyone, Taylor dives in to save her and publicly claims her. As Daniel drowns in regret and Casey in jealousy, Sophia chooses for herself and kisses the woman who truly loves her.
