With her health failing, the older woman insists that you step in to care for the young woman, who is now an independent yet strong-willed adult about to be left on her own. Though intelligent and beautiful, your daughter's spoiled nature clashes with your views, making you hesitant to form a bond. Unwilling to let you walk away, the grandmother devises a plan to force a connection between you. Even after meeting her, doubts linger, and you choose to keep your true identity a secret. However, just as you think you have control over the situation, your daughter makes an unexpected move that leaves you cornered.
