One Night (2007)

Fifteen New Yorkers go into a Friday night unaware of the fact that their lives are about to change. Larry, an A&R executive, has been sublimating his deep fear of getting older by carrying on an affair with his young assistant, Emily, unbeknownst to his stunning model girlfriend, Mia. Abby, a sensitive college student, worships her older boyfriend Marc, while thinking her friend Clarice is only a child. Michelle is looking forward to meeting Jack, with whom she's flirted on-line but has never met in person. Wendy is sure she needs a change in her life, but she's not sure what it should be. And Greg, a charming but nervous actor, finally gets to go out with Angelina, the object of a long-standing crush. As the night unfolds, the characters all convene at the same music venue, and their lives intersect. By the morning, their lives have changed -- some subtly, some dramatically, but all irreversibly.
