Majority of the movie is a woman and her family trying to follow and figure out where her husband is going, eventually finding him at a party and confronting him with a suspected affair.
Basically most of the movie! The plot revolves around a young woman chasing her husband across the city because she suspects him of cheating on her. There’s numerous coiled in the film (her parents, her sister and her partner, etc.) and someone in all of the couples at one time or another seem to flirt with or show interest in someone outside of their relationship. At one point her sister actually kisses the other guy she was flirting with and is later caught by her boyfriend calling him.
Sort of? At one point the mother chases a car down the road and ends up passing out, can be interpreted like she lost her breath/was winded and got light headed.
In the very beginning two characters kiss a bit and try to have sex, nothing is shown and they’re mostly talking about why they’re going to not have sex. Outside of that one character describes a one night stand with not a lot of detail and people occasionally kiss/make out lightly but nothing wild.
