About the title
New Year's Eve, 2000. Things aren't going well for 36-year-old anesthesiologist Millie. First, a pregnant patient's husband turns out to be her ex-boyfriend, then her friends ask her to move out, and at the New Year's party — which Millie attends hoping to rekindle things with Joe, her great college love — it turns out he has brought a new girlfriend and is about to propose to her. Unable to bear it, Millie takes a second sip from the bottle of tequila she was given the day before and is transported back to the exact moment she took the first sip — the beginning of the party. She decides to use the magical drink to change her fate and win Joe back.
