Claire thinks she's being set up with a charming stranger at her best friend's wedding. Julian thinks the same thing. Neither of them expects to lock eyes across a terrace and realize the "stranger" is the person who's haunted their thoughts for a year. She's carrying a secret about what happened after their night together. He's been trying to find her since she disappeared. Now they have one week to figure out if what they had was real—or if some moments are meant to stay perfect in memory.
