When Mallory’s boyfriend, Jeremy, cheats on her with an online girlfriend, Mallory decides the best way to de-Jeremy her life is to de-modernize things too. Inspired by a list of goals her grandmother made in 1962, Mallory swears off technology and returns to a simpler time (when boyfriends couldn’t cheat with computer avatars). The List:

1. Run for pep club secretary
2. Host a fancy dinner party/soiree
3. Sew a dress for Homecoming
4. Find a steady
5. Do something dangerous But simple proves to be crazy-complicated, and the details of the past begin to change Mallory’s present. Add in a too-busy grandmother, a sassy sister, and the cute pep-club president–who just happens to be her ex’s cousin–and soon Mallory begins to wonder if going vintage is going too far.
