After a dumpster fire of a Valentine's Day, Emilie Hornby escapes to her grandmother's house for some comfort. She passes out on the couch, but when she wakes up, she's back home in her own bed-- and it's Valentine's Day all over again. And the next day. And the next. Emilie is stuck in some sort of time loop nightmare: re-watching her boyfriend, Josh, cheat on her day after day. And she keeps running into Nick-- sometimes literally-- in unfortunate ways. When something good starts to come out of these terrible days, what happens when the universe stops doling out do-overs?
