A high-school senior loses her little brother while trick-or-treating, and recruits three of her classmates to help bring him back home before her mother finds out in "Fun Size," a teen comedy from first-time director Josh Schwartz (executive producer of TV's "Chuck" and "Gossip Girl").
Sardonic Wren (Victoria Justice) hails from an unusually dysfunctional family. She can't wait until she escapes to college and leaves them all behind, but in the meantime, an invitation to the biggest Halloween party in the area at least offers her an excuse to get out of the house for a night.
But when Wren is placed on babysitting duty so her mother can dash out and party with her handsome young boy toy, the dejected teen reluctantly takes her little brother Albert out for a night of trick-or-treating. Later, when Albert vanishes into a sea of costumed kids, his panicked sister enlists the help of her best friend April, wannabe womanizer Peng, and his charmingly geeky pal Roosevelt to track down her missing brother, and get him safely back home while their mother remains none the wiser.
Meanwhile, over the course of one wild and unpredictable Halloween night, the group's frantic search lands them in some pretty outlandish situations, and provides Roosevelt with the perfect opportunity to impress his longtime crush Wren.
