One scene where Charlotte implies that she "lost her inhibitions" with a man. Very oblique

No profanity

There's A LOT of smoking in this film, even for the time period, even for a Bette Davis film. Paul Henreid does that famous cigarette thing where he lights two and passes one to Bette Davis, then they blow smoke in one another's faces.

Reference to alcohol helping a young woman lose her sexual inhibitions.

Car accident (not at all graphic)

Charlotte's mother is very domineering, and her conversations with Charlotte make the suggesting that if Charlotte doesn't "conform" to her mothers wishes, she will be disinherited.
