Victoria Justice is Wren, a teenage girl trying her best to fit it. Her girlfriend April (played by Jane Levy) tells her they have to find a way to get into the high school Halloween party being thrown by the hottest young man Aaron (played by Thomas McDonell) at the school. While they are discussing how they can get into the party and what costumes they will wear, Wren does a weird dance that attracts the attention of Aaron driving by. He stops to say hello and personally invites Wren to the party. April cannot believe what just happened, as they will finally be part of the cool kids at school when they go to the party.
Wren comes home to find out her mother, Joy (played by Chelsea Handler) is going out with her much younger boyfriend, who she took up after her father died. She announces she is leaving Wren in charge of her little brother, Albert (played by Jackson Nicoll) for the night. Wren pleads to get out of it, but her mom promises to sign the student loan application for NYU that Wren wants to attend after high school as long as Wren agrees to watch over her brother. Wren's brother is about eight-years old. He does not speak for reasons unexplained. He dresses as Spiderman, Wren as Dorothy from OZ, and April dresses as sexy kitty. Wren convinces her friend Roosevelt (played by Thomas Mann) to ask his two moms if he can take them out in the car. Roosevelt has this strange conversation with them using ancient Greek, while the cat has an allergic reaction to the smell of Nair that April admitted earlier she used on her butt, which has made her rear-end feel like it is on fire. Even though they cause a cat emergency, the moms don't know what caused it, and Roosevelt is able to take the car. It is a bright-yellow colored Volvo that has a problem with the alternator and therefore stalls out in traffic, right in front of the two biggest high school jocks that are behind them in a truck. During the turmoil, as they barely escape, Wren loses her younger brother, Albert, who wanders off seeking candy.
Albert walks in to a convenience store and makes friends with the clerk named Fuzzy (played by Thomas Middleditch). Fuzzy, having no friends and also having lost his girlfriend to a fat ninja guy, asks if Albert will help him get revenge. Albert agrees by nodding his head and goes along for the ride. When Fuzzy attempts revenge, he almost sets the house on fire and gets caught by the fat ninja guy. While they are fighting, Fuzzy's car is towed away with Albert inside. Albert gets out of the car when he sees the chicken shack restaurant which is his favorite. He meets some party girls there who end up taking him to the high school party.
Wren is in a panic looking for the missing Albert, but correctly thinks he would likely go to the chicken shack so they head there. The high school jocks catch up with them. Roosevelt trying to escape, floors the gas, but the car is in reverse. The car crashes backwards into the restaurant knocking the large chicken down from the roof which falls on the top of the car looking like it is humping the car.
Wren gets a call from April telling her "he's" at the party. Wren thinks she means Albert but April means Aaron. Wren rushes to the party but Albert has already left seeking to get revenge on the guy that stole his candy. This mean guy catches Albert instead and calls Wren to tell her he is holding her little brother to turn over to the police because he put a bag of dog poop containing exploding firecrackers on his front porch. Wren goes to rescue her little brother, but it is Fuzzy that shows up to save the day distracting the police by running away naked in front of them, so Wren and Albert can get away. Wren decides she would rather have Roosevelt as her boyfriend than Aaron. Upon learning this Roosevelt convinces his two moms to let him go to her to profess his love.
Best part of story, including ending:
Albert, the younger brother of Wren, gets away with all of his pranks and adventures, and is not harmed even though he is wandering around alone.
Best scene in story:
One funny part is because Wren's mom, Joy, goes to the party with her much younger boyfriend, it is full of high school idiots. One guy takes her cell phone and farts on it. Joy realizes that she fits in better with older adults when she finds the parents in their bedroom while looking for the bathroom and has tea with them.
Opinion about the main character:
Wren turns down the advances of the super cute high school guy to go instead with her nerdy friend Roosevelt. This doesn't seems all that plausible.
