“The Slumber Party” depicts the hilarious aftermath of a sleepover birthday party hypnotism gone wrong as best friends Megan and Paige, along with soon-to-be step-sister Veronica, wake up with absolutely no memory of the night before. Now they must retrace their steps to find missing birthday girl Anna Maria … and explain why there’s a flock of baby ducks in the bathtub, what happened to Megan’s left eyebrow, and why she’s wearing unattainable hottie Jake Ramirez’s signature black hoodie.
