Confessions of a Sorority Girl

Sabrina helps Tina hide her pregnancy to earn her trust, but it's a calculated move to gain a loyal ally within the sorority. Tina confides in Sabrina about her unwanted pregnancy and possible abortion, and Sabrina uses this vulnerability to position herself closer to power. This manipulation allows Sabrina to build a false sense of loyalty that she can later exploit for her own schemes.

Sabrina wins the presidency through a combination of strategic manipulation. After being nominated by Tina and Ellie, she realizes her French grade is the deciding factor, so she seduces her French teacher and then uses that encounter to blackmail him into giving her a better grade. She then threatens to expose Rita's personal secret about her mother being in jail, forcing Rita to step aside. This ruthless approach replaces the legitimate election process.

Sabrina threatens to reveal that Rita's mother is in jail, using this deeply personal and painful information to force Rita to give up the sorority presidency. The secret preys on Rita's vulnerability and fear of social exposure, making it a powerful tool in Sabrina's campaign to seize leadership. This cruel act demonstrates Sabrina's willingness to exploit anyone's private struggles for her own advancement.

Despite openly disparaging Sabrina and warning she's bad news, Mort eventually succumbs to her advances during a late-night encounter at his bar. The summary indicates Sabrina seduces him and they sleep together. While his initial resistance suggests he recognizes her manipulative nature, he ultimately fails to maintain his boundaries, leading to consequences that damage his relationship with Rita.

Sabrina sets fire to Mort's bar during a climactic confrontation after her schemes unravel. Her manipulation of Rita has been exposed, Mort has rejected her, and she's lost control over the situation. In a desperate and violent act, she locks Rita and Mort inside the bar and ignites the fire, resulting in their rescue by Jimmy but leaving Sabrina to face arrest for arson and endangerment.

Sabrina is arrested at the end of the movie for arson and endangering others. After setting fire to Mort's bar and locking Rita and Mort inside, she's left to answer for her actions as the authorities close in. The ending shows the consequences of her toxic behavior, with the film emphasizing that her manipulative schemes ultimately lead to her downfall.

Sabrina's mother sends her to live at the Alpha Beta Pi sorority house because she believes Sabrina is too spoiled and troublesome to stay at home. Mrs. Masterson wants Sabrina to learn discipline and humility, even comparing her unfavorably to her older sister Julia, who was a former sorority president. This punishment sets the stage for Sabrina's entry into the sorority where she causes chaos.

Sabrina spreads rumors about Rita as part of her strategy to undermine Rita's relationship with Mort and damage her reputation within the sorority. She reveals Rita's secret about her mother being in jail in an attempt to drive Mort away from Rita. This tactic is designed to create jealousy and fracture the connection between Rita and Mort, allowing Sabrina to position herself as a more desirable alternative.

Rita has a difficult relationship with her mother, who is often too preoccupied to listen to her. Rita shares these personal struggles with Sabrina, revealing the vulnerable side of her life. This becomes the exact information Sabrina later weaponizes against her, using the fact that Rita's mother is in jail as blackmail material to force Rita out of the sorority presidency.

Sabrina's relationship with her mother is strained and emotionally distant, which drives much of her destructive behavior. When Mrs. Masterson visits and criticizes Sabrina, comparing her to her successful sister Julia and cutting her allowance, Sabrina returns to the sorority resentful and more determined to seek power and control elsewhere. This maternal rejection fuels Sabrina's cold manipulation of others as she seeks validation and influence.
