The movie depicts the hilarious aftermath of a sleepover birthday party hypnotism gone wrong as best friends Megan (Darby Camp) and Paige (Emmy Liu-Wang), along with soon to be step-sister Veronica (Alex Cooper Cohen), wake up with absolutely no memory of the night before.
Now they must retrace their steps to find missing birthday girl Anna Maria (Valentina Herrera), 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 (Ramon Jose Rodriguez) signature black hoodie.
