There is no kid who doesn't like dressing up during the Halloween and going on a hunt for candies with a trick-or-treat bag in hands. And as the kids grow old, some things change, but this tradition keeps on going. The costumes are a bit different and the company as well.. and trick-or-treat turns into a hot party for teenagers.. But, in the core, it's all there. And Wren (Victoria Justice) is a high school student who was really looking forward to this one, because she and her best friend April (Jane Levy) were invited to a party whose host is a very cute guy from school. So, the two of them got all fixed up, prepared to have all night fun.. Until Wren's mother told her, in the last moment, that she is to babysit her little 10 year old brother. Yeah, that's a thrill. The two of them take young Albert (Jackson Nicoll), who is in costume of a Spiderman, and somehow manage to lose him in the sea of all other kids in costumes. And night filled with dreams and hopes for a hot party really quickly turns into a disaster and chasing after a 10 year old. And it is Wren's obligation to find him before her mother finds out about everything. Along the way, she and her best friend get into lots of hilarious situations, which make this simple plot a comedy to die of.
