The scene is significant because it shows the breakdown of Ace and Ginger's relationship and highlights the destructive nature of their addiction to drugs and gambling. The argument escalates, and Ginger becomes violent, throwing objects at Ace and eventually storming out of the room. She then accuses Ace of being involved in illegal activities, including his own gambling operations.
Ginger becomes defensive and denies any involvement in the drug trade. Ace tells her that he knows about her drug use and that he has proof, including photographs of her with a known drug dealer.
There is a scene in which Sam 'Ace' Rothstein (played by Robert De Niro) and his wife Ginger (played by Sharon Stone) are in their bedroom, and Ace becomes angry with Ginger for her past involvement in the drug trade.
