The first story focuses on a teenaged science whiz at Waterbury High School named Jake Logan (Nick Robinson) who is best friends with his dog, Murray (Winston).

The second story focuses on two teens, Avalon (Bella Thorne) and Halley (Zendaya) who co-created a web magazine called "GeeklyChic."

In the school library, Halley receives a call from her and Avalon's favorite New York City publishing company, Burns Publications, run by the stunning Cherie St. Claire (Jessalyn Wanlim).

Halley believes her fashion-forward older brother Kendall (Jascha Washington) is playing a prank on her until she sees him doing a service project out on the school grounds and realizes the call from Cherie is real.

Back at school, Avalon encounters classmate Walker (Connor Price), who puts her in contact with a French singer named Jean Frank.

In a surprise twist, Jean reveals to the girls that he is actually Johnny Frankewski, an American, and Halley and Avalon then decide they will co-write the article and share the byline.

The move angers Cherie who decides not to hire either Avalon or Halley, but the TV show "Teens Now" picks up the article about Johnny and changes his image, revealing his ruse as a singer from Paris.

"Teens Now" also broadcasts the GeeklyChic blog for their audience, leading to the web magazine going global, and Avalon and Halley make up as best friends again.

The third and final story of the film focuses on Savannah and Emma, teenage alter egos (both roles played by Mary Mouser) who trade places because they each believe the other's life is better.
