Peter receives a letter from a certain person from his past. A girl he babysat as a favor to a family friend. She reveals that she had been listening his music for years. This makes him happy. Then he finds out a butterfly killing fact. She is getting married in a few weeks. Everyone is at the hotel they used to go to on vacations. He once promised to walk her down the isle because her father passed away and asked him to do so. But a certain phrase she uses leads him to believe she is in danger. Will Peter be able to save her? Will a romance begin between the two? Or will the old saying Till Death Do Us Part come into play a lot sooner than either of them anticipated?
