# The Key - Parental Guide
This 1940s drama about a married couple rekindling their romance contains moderate sexual content and adult themes about intimacy and fidelity. There's no violence, language, or scary elements, but the focus on sexuality makes it better suited for mature teens and adults rather than younger children.
Synopsis
In 1940s Venice, after twenty years' marriage, retired art critic Nino Rolfe and his younger wife Teresa feel their passion waning. To help her shed her inhibitions and rekindle their relationship, the professor records his sexual fantasies in a diary.
