The Next Morning (2018)

Lena moves to a new city and, feeling lonely, she goes to a bar, hoping she'll meet some new people and, ideally, get a little action. She hooks up with a handsome stranger and takes him home for the night, then kicks him out abruptly in the morning - this was supposed to be nothing more than a one-night stand. Later that morning, Lena starts her new job, and when she arrives, she discovers that last night's hookup is her brand new boss!
