Married for five years, Sophia discovers her husband Daniel has long been cheating with her younger sister Casey. She fakes amnesia after a car accident to test them. To cut ties, Daniel lies and claims she is the wife of her elder sister Taylor.
Taylor, who fell for Sophia at first sight, plays along and stays by her side. She tempts Sophia step by step — from bold kisses to intimate nights — until Sophia falls completely.
When Casey shoves Sophia into a pool in public, Taylor leaps to save her and claims her openly. Daniel is consumed by regret, while Casey goes mad with jealousy. In front of everyone, Sophia takes the initiative to kiss the woman who truly loves her.
