This is the story of 23-year-old Laura who lives in the largest city in the world and yet feels alone. She also knows the exact date in which she'll die: April 30. What Laura doesn't know is what she'll do from now till then, and thus she enrolls in a group of optimists, which she finds pathetic but fun. In that group she writes a list of 10 things she wants to do before she dies, some that mean a lot and some that are a lot of fun. The first thing on her list is to save a life.
