Natalie and Kaitlin go into their 20s living separate and faraway lives. Kaitlin comes home from New York for christmas every year, and they hug and talk into the night, falling asleep spooning like they did when they were little girls. Kaitlin makes a grand gesture and buys tickets to go on a special sister adventure: to the Jem and Holograms Convention. What ends up happening at the convention is something neither of them saw coming.
