Gemma is making a name for herself in the music biz in LA. She's also got a "no musicians" rule when it comes to dating. That might be because her rock star ex-boyfriend used her to get a record deal from her rock legend dad, though it's impossible to say for sure. So, when Gemma crashes (literally) into Jack one Friday morning, at first she feels like fate might have finally decided to do her a favor. After all this guy is cute cute and, wait, is she imagining it or is he staring a little too deeply into her eyes? She'd think he was stalking her if she wasn't getting a funny feeling of dejà vu every time she looked at him. The truth? This is no ordinary Friday. Not for them. In fact, they've lived this day over and over 147 times. Luckily, Jack has a theory to bring his own personal Groundhog Day to an end. All Gemma has to do is fall in love with him in 24 hours.
