Nancy, a bar girl, encounters Simon’s influential uncle, Mr. Sawyer, who leads an exclusive club with an elite-only Bauhinia Hall on the 78th floor. Nancy learns that despite their wealth, even Simon’s circle cannot access this space because of rigid class barriers. An offended colleague mocks Nancy’s low status, but Simon unexpectedly transfers her 700,000 dollars, angering his partner Nancy Snyder. Simon then offers Nancy a chance to become his 'sidekick,' a kept woman in their social circle, introducing a risky new role for her amid the stark class divide.
