Preferential Treatment

Sandra and Tina are two high school girls who never saw eye to eye. They constantly argue and clash at school. Eventually, their teacher intervenes.
During the discussion, Sandra accuses Tina of bullying her because of her sexual orientation. Tina vehemently denies it, but their teacher, who's also a lesbian, seems inclined to believe Sandra. Tina, feeling the pressure, comes up with a risky strategy to turn the situation around quickly.
With Sandra watching closely, Tina fabricates a story about questioning her own sexuality and starts to seduce their teacher as a distraction. Although Sandra sees through Tina's scheme and protests, their teacher silences them. It becomes obvious to both girls that they need to do more to manipulate their teacher's biases and win her favor.
