As Summer Heights High School begins a new term, we meet the primary subjects of this 'documentary' series: disruptive Tongan student Jonah; deluded drama teacher Mr. G; and self-absorbed exchange student Ja'mie.
Ja'mie scales the social ladder on her first full day at school; Mr. G makes the most of an unexpected promotion; Jonah joins an ethnic-acceptance program to curb his behavior and improve his academics, with mixed results.
Ja'mie undermines her relationship with her new friends; Mr. G holds auditions for his new musical; a suggestive drawing puts Jonah's irate father on the defensive.
Mr. G is forced to make concessions in the school play; Jonah and his pals agree to mentor a group of Year 7 students in exchange for a break-dance performance; Ja'mie lobbies for a first-ever Year 11 formal.
Parental objections force Mr. G to overhaul his musical 10 days before the premiere; Ja'mie makes a surprising date choice for the Year 11 formal; Jonah's ongoing turf war with Year 7 hecklers lands him a suspension.
