After she spends a perfect day with her otherwise moody and miserable boyfriend, Rhiannon discovers that for that one day, his body was inhabited by another boy. Every day is the same for Rhiannon. She has convinced herself that she deserves her distant, moody boyfriend, Justin. She knows the rules: Don't be needy. Avoid upsetting him. Never get your hopes up.
Then, out of the blue, they share a perfect day together - perfect, that is, until Justin doesn't remember anything about it. Confused, and yearning for another day as great as that one, Rhiannon starts to question everything. And that's when a stranger tells her that the Justin she spent that time with... wasn't Justin at all.
