Inspired by Disney Channel's High School Musical film franchise, High School Musical: The Musical: The Series is a scripted, mockumentary-style show that follows students at a fictionalized version of Salt Lake City's East High School, where the original films were shot. The first season centered on the school's first-ever production of the stage adaptation of High School Musical, while the second season saw the drama department take on Disney's Beauty and the Beast. The series' third season, which premiered on Disney+ July 27, followed the Wildcats to Camp Shallow Lake, where they performed Disney's Frozen.
