In the heartland of South Dakota, Sunny, a sheltered Indian teenager, finds herself under the influence of her rebellious friend Lupe. Feeling compelled to throw a party while her mother is away on a business trip, she hopes to captivate her crush, Hunter. However, as the night unfolds, Sunny's plans go awry when she discovers Hunter leaving the party in the company of Emma, a popular girl. In a moment of confusion, she ends up in a compromising encounter with her eccentric and devoutly Christian friend Kyle, both of them quickly realizing it was a mistake.
The next morning, Sunny confesses to Lupe that she has lost her virginity, but discreetly omits the identity of her partner, leading Lupe to assume it was Hunter. The situation escalates when Sunny realizes that she has inadvertently left in place the condom Kyle used, igniting her fears of an unexpected pregnancy. Seeking a solution, the friends set out for the local pharmacy to get a Plan B pill, only to find themselves denied service. Acting on Lupe's advice, they decide to take a road trip to the nearest Planned Parenthood in Rapid City, all while using Sunny's mother's car.
Their journey takes an unexpected turn when they get lost, prompting the girls to seek guidance from a friendly clerk at a convenience store, who points them toward her cousin, a local drug dealer. In a desperate situation, they confront the dealer, who offers them fake IDs in exchange for sexual favors. A chaotic encounter ensues, but they cleverly manage to escape with the IDs and an unmarked "birth control pill," which they later learn is not what they thought it was.
After an intense evening, they find themselves at a bowling alley where Lupe intends to meet a mysterious guy named Logan she has been chatting with online. To Sunny's surprise, Hunter is also at the bowling alley, and he invites her to join him at a diner. Meanwhile, Lupe's encounter reveals Logan to be a female drummer, leading to a surprising turn of events between her and Sunny’s car.
With a mix of tension and heartfelt moments, the girls are soon faced with the grim realization that their car has gone missing, leading to emotional confrontations and the discovery of the truth behind their sexual encounters. Amidst the chaos, both girls begin to confront their identities, make promises to stop lying to each other, and seek a way forward.
Their journey climaxes as they arrive at Planned Parenthood, only to be devastated by its closure, forcing Sunny to confront her need for her mother’s support. Navigating a maze of emotional hurdles, both girls return home, each facing their own parental challenges. Lupe finds unexpected warmth and understanding from her father, while Sunny's mother, initially upset, ultimately comes around after Sunny expresses her feelings of pressure and the need for the morning-after pill. This fateful journey not only tests their friendships but brings to light the true beauty of connection, vulnerability, and unconditional support between friends and family.
