Een sarcastische tiener (Victoria Justice) raakt in de problemen doordat haar broertje, waarop ze aan het passen is, plots verdwijnt tijdens 'trick-or-treating' op Halloween avond. Ze moet noodgedwongen een beroep doen op haar beste vriend en een aantal 'niet zo leuke' kinderen om zo haar broertje weer te vinden voordat de nacht over is.
