Big sister Kennedy and little sister Devon couldn't be more different. Their shared room has a clear divide down the middle. On one, musical theater-loving Kennedy keeps things tidy. On the other, heavy metal fan Devon looks like she lives in an exploded toy store. When baby sister Eve moves in, her contribution is crying. Constant. Ear-piercing. Crying.

The added stress pushes the older girls to their breaking point, and they get into their biggest fight yet. In response, Mom and Dad crack down, seizing all beloved electronics until Kennedy and Devon can find a way to get along. Now stuck together with no distractions except Eve's screaming, the two land on a desperate solution: tell Eve a bedtime story so epic that it puts her to sleep and gets her big sisters out of trouble.

Pizza aside, the only thing the girls have in common is their love of stories. But Kennedy's fairy tales make Devon want to barf, and Devon's nonsensical adventure stories make Kennedy want to tear her hair out. So they try to mash-up a story of true love, adventure, princesses, pirates, pirate-princesses, dragons, spiders, and...garbage trucks?

That's a lot of story to spin. Will their hilarious fairy tale remix solidify their sisterly bond or break it forever after?
