Beverly Hills, 90210 - Season 3 Episode 28 Something in the Air

Donna is suspended, and must enroll in summer school before she can graduate. Felice refuses to appeal the ruling because she is worried about her own reputation. Donna changes her mind by reminding her that her husband and Donna forgave Felice for her past mistakes. Brandon is disgusted by the students' apathy, and Gil encourages him to take action on Donna's behalf. Brandon convinces the entire senior class to walk out on finals as a show of solidarity. Dylan doesn't want to participate because he has set his sights on making it into the University of California-Berkeley. The juniors join the protest after Brandon agrees to add the elimination of a proposed dress code to the demands.
