This film about couples and how people who love each other get along sends a mostly positive, if comic, message about long-term relationships.
The couple at the center of the film suspects their neighbor has murdered his wife and spend much of the film wondering if any foul play has actually occurred. By the end, there's a dead body, a chase scene, and some comic gunplay.
No sex, though some discussion of sex and suggestive comments.
Occasional swearing, including "s--t" and "damn."
Some social drinking at restaurants and small gatherings in apartments.
