Each episode of "I Didn't Do It" starts at the end, sort of. As the episode begins, an adventure has just ended for a group of five teenage friends. The gang then tries to explain, through flashbacks, exactly what happened on their adventure that inevitably went haywire. Booksmart Lindy is the quick thinker of the group who often saves the day when they are in trouble, while her confident twin brother, Logan, has street smarts. Fashionista Jasmine, voice of reason Garrett and oddball Delia are the twins' friends who make up the rest of the group.
