A 16-year-old international assassin yearning for a "normal" adolescence fakes her own death and enrolls as a senior in a suburban high school. She quickly learns that being popular can be more painful than getting water-boarded.
Nothing like this happens - but FYI a girl is left unconscious at a party, which could have gone a totally different direction but thankfully didn't / she's ok.
There's a teacher that is inappropriate toward the popular guy, played off as a running joke but could be triggering to some and is problematic behavior.
There's a teacher character that's a little icky. On her first day of school, another student smacks her on the rear and says 'fresh meat!' it happens a couple other times in the film, once where she swiftly defends herself, another that seems consensual, and i think once with the teacher and the popular boy. When chaperoning the dance, the teacher comments on a student's neckline. Most of this is played off as fine/jokes but still FYI.
a teen has her butt slapped by another teen she's never met. later in the movie there is a one-off line about how a man lost his virginity to a 65-yo woman
