The series follows the adventures of Tori Vega, a teenager who is accepted into Hollywood Arts High School (a school for talented teens in various performing-arts fields) after taking her older, much less-talented sister Trina's place in a showcase after Trina has an allergic reaction to a Chinese herb gargle designed to help make people sing better. The plot follows Tori as she finds her place within Hollywood Arts while getting into crazy situations and adventures, and meeting friends to help her along the way. Other students at Hollywood Arts, and the students who make up Tori's group of friends, include Andre Harris, a musical prodigy who becomes Tori's best friend at Hollywood Arts after encouraging her to stay at the school and helping her realize her talent; Robbie Shapiro, a socially awkward ventriloquist who carries around his puppet Rex Powers, who is seen by Robbie (and generally everyone else) as a living person; Jade West, a sarcastic and Gothic "mean girl" who has a complicated frenemy relationship with Tori and often threatens her; Cat Valentine, a sweet and innocent but naive and somewhat dim-witted girl; and Beck Oliver, a down-to-earth and handsome guy who is Jade's boyfriend. They have been a couple since before the start of the series until the Season 3 episode "The Worst Couple", but got back together in the Season 4 episode, "Tori Fixes Beck and Jade". Beck and Tori have also had moments where they were attracted to each other (they almost kissed twice), but Tori did not want to risk her small friendship with Jade over this. Other characters include Erwin Sikowitz, the performing-arts teacher for Hollywood Arts; Lane Alexander, the school's guidance counselor; and Sinjin Van Cleef, an odd classmate who is mostly in charge of A/V.
