Plot Synopsis

Created and executive produced by writer Terri Minsky, ANDI MACK is a half-hour comedy series that centers on Andi Mack, a girl whose life goes from routine to roller coaster overnight. In the serialized story, Andi is contemplative and artistic and sheltered by overprotective parents. But on the eve of her 13th birthday, Andi's free-spirited older sister Bex returns home with a revelation that changes everything, and sends Andi on an uncharted course of self-discovery. At least she's in good company; her best friends, Cyrus and Buffy, are also figuring out their places in the world. Along the way, Andi learns that sometimes the unexpected is what makes life great. Andi was raised in a loving yet overprotective home. Now, with Bex's encouragement, she begins to step outside her comfort zone, particularly when it comes to approaching the most intriguing guy at Jefferson Middle School -- Jonah Beck, whom she quickly realizes is dating a high school girl, Amber. Andi proves that her greatest strengths may be how she accepts life's unpredictability with optimism. She also finds solace by tapping into her creativity in her backyard hideaway, the Andi Shack. On Friday, April 7, 2017 at 8:30pm ET/PT, Disney Channel premiered ANDI MACK, showing a one-hour series opener. In the series debut, "Tomorrow Starts Today," Andi's family life is thrown for a loop when her big sister, the freewheeling Bex, returns home on the eve of her 13th birthday. It begins with Bex arranging for Andi to train for Ultimate Frisbee with the cutest guy at school, Jonah Beck, who she learns has a high school age girlfriend, Amber. Andi also grapples with telling her best friends Buffy and Cyrus some big news, but is preoccupied making Jonah Beck a bracelet, at his request. Meanwhile, Cyrus becomes the Space Otters' official Enthusiastic Supporter and helps them win their first game.

Disney Channel premiered Season 2 of ANDI MACK on Friday, October 27, 2017 from 8-9pm ET/PT. The first season introduced Andi on the eve of her 13th birthday just as she learns that her older sister Bex is actually her mother. This revelation puts Andi on an unfamiliar path of self-discovery which she navigates with the help of her two best friends, Cyrus and Buffy, and her loving family.
