Confessions of a Sorority Girl

Sabrina Masterson arrives at the Alpha Beta Pi sorority house as the new roommate of Rita Summers. Her wealth and vanity immediately mark her as a disruptive outsider in the close-knit sisterhood. She is welcomed, but it’s clear her presence will shake Rita's world.

Sabrina takes an interest in Mort, the owner of a beachside bar, and begins flirting with him. Mort shows clear indifference, which only fuels Sabrina's resolve and stirs trouble within Rita's circle. The tension between Sabrina, Mort, and Rita starts to mount.

Mrs. Masterson makes a surprise visit and expresses disappointment in Sabrina's behavior. She insists Sabrina should be more like her older sister Julia and cuts Sabrina's allowance for breaking rules. Sabrina returns to the sorority with a resentful, scheming mindset.

Sabrina helps Tina hide her pregnancy and avoid getting caught, earning Tina's trust. The act reveals Sabrina's willingness to manipulate others to stay on top. Tina begins to view Sabrina as someone who can shield her from consequences.

Ellie and Tina nominate Sabrina for sorority president, setting up a contest against Rita. Sabrina discovers the presidency hinges on her French grade and a willingness to bend rules. The race becomes a sharper test of Sabrina's ambition.

To secure the required French grade, Sabrina seduces her teacher and later uses that encounter to threaten him. The stunt marks a steep ethical tumble and deepens her estrangement from the other sisters. Her plan to win the presidency grows more ruthless.

That night, Sabrina pressures Rita to relinquish the sorority presidency, threatening to reveal that Rita's mother is in jail. Rita is stunned by the attack on her personal life and the political maneuvering inside the sorority. The two women's conflict widens into open hostility.

The next day, Sabrina learns that her mother remains distant, and Mort openly disparages her. Seeking some relief, she turns to Mort for support, but his scorn only fuels her resolve. The friction between Sabrina and Rita grows as personal alliances shift.

Sabrina reveals Rita's secret about her mother in an attempt to derail Rita's relationship with Mort. Mort reacts with anger, and Rita is left reeling from the betrayal. The scheming escalates as Sabrina doubles down on manipulating both Mort and Rita.

In Mort's bar, Sabrina seduces Mort and the two sleep together after an initial resistance. The act solidifies Sabrina's bid for control over Mort, but it also threatens to explode the fragile dynamic among the sorority members. The encounter further complicates Sabrina's relationship with Rita.

The next morning, Sabrina reveals to Mort that she slept with him, and Mort admits the truth. Rita is furious and slaps Mort, while Sabrina expects them to be together. Mort warns that Sabrina is bad news and vows to regret the affair.

In a climactic confrontation, Sabrina locks Mort and Rita in Mort's bar, sets it on fire, and watches as the place fills with smoke. They are rescued by Jimmy, but Sabrina is arrested for arson and endangering others. The chaos marks the collapse of Sabrina's scheme and the end of her control over the situation.
