During the opening credits, the Ronettes serenade us with Be My Baby as images of couples twirl together in harmony. As the music fades, radio DJ Cousin Brucie announces the next track, the Four Seasons' Big Girls Don't Cry, which lingers as the film unfolds.
This story is set in the summer of 1963, centering on Frances "Baby" Houseman (played by Jennifer Grey), who is traveling in the backseat of her family's car. Baby, along with her affluent Jewish family, is on their way to Kellerman's Mountain House, a Catskills resort where her father, Dr. Jake Houseman (portrayed by Jerry Orbach), serves as the personal physician to Max Kellerman (played by Jack Weston), the resort owner.
On arrival, Baby and her older sister Lisa (played by Jane Bruckner) participate in a merengue lesson led by the talented former Rockette Penny Johnson (Cynthia Rhodes). As evening falls, Baby sneaks into the main house where she overhears Max instructing the waiters to ensure that all young women, “even the dogs,” have a good time. When the entertainment staff arrives, including the enigmatic Johnny Castle (played by Patrick Swayze), Max sets down the rules: teach the guests to dance but keep everything appropriate, much to Johnny’s silence.
At dinner, we discover Baby's aspirations: she is enrolled to study economics at Mount Holyoke College and intends to join the Peace Corps, while Lisa dreams of being an interior decorator. Max introduces the sisters to his grandson, Neil (Lonny Price), who studies hotel management at Cornell. After an uncomfortable dance with Neil, Baby hears Johnny’s mambo track, watching him and Penny’s luxurious dance, which Max disrupts to remind them of their purpose.
Eager to escape Neil’s stale company, Baby sneaks into the staff quarters, drawn by the sultry music of “Where Are You Tonight?”. There, she meets Johnny's cousin Billy Kostecki (Neal Jones) and helps him carry watermelons to a staff party where she is overwhelmed by the sight of couples engaging in dirty dancing to "Do You Love Me?". Enchanted by Johnny's charisma, Baby finds herself captivated, and he teaches her some of the finer points of dirty dancing.
The following evening, while taking a stroll with Neil, Baby spots Lisa and Robbie Gould (Max Cantor), a Yale medical student and waiter, amidst a quarrel stemming from Robbie’s indecent advances. Later, Baby discovers Penny in distress in the kitchen, and learns that she is pregnant, mistakenly believing Johnny is the father. When Baby confronts Robbie about his role in Penny's situation, he coldly dismisses her, prompting her to take action.
Determined to help Penny, Baby seeks out her father for $250, reluctantly sharing a glimpse of the dire situation Penny is in. After a few questions, he hands over the money. She returns to give it to Penny, who initially refuses. However, realizing the urgency, she ultimately volunteers to fill in for Penny’s dance gig with Johnny—to whom she’s drawn more than she realizes.
Their dance journey begins slowly—full of sweet struggle—under Johnny's patient mentorship. After moments of conflict and fiery exchanges, Baby’s determination earns Johnny's respect, and they practice lifts in a picturesque meadow. The blossoming intimacy between them further intensifies as they share quiet moments, leading to a passionate night together.
Tragedy strikes soon after as Penny suffers complications from her abortion, and Baby’s father rushes to help, mistakenly believing Johnny is responsible for Penny’s plight. After saving Penny's life, Dr. Houseman forbids Baby from seeing “those people,” but her burgeoning feelings for Johnny compel her to defy him.
As the story unfolds, Baby navigates family expectations, her love for Johnny, and the harsh realities of class differences and manipulation around her. The resort’s finale showcases Johnny's defiance after being wrongfully accused of theft, leading to his firing. However, Baby—standing true to her principles—steps forward and declares the truth in front of everyone, culminating in Johnny retrieving her from the sidelines with those legendary words: > “Nobody puts Baby in the corner.”
The two perform their dance to I've Had The Time of My Life, enveloped in wild energy as the entire hall comes alive, symbolizing a break from the past and a celebration of freedom and love. Ultimately, the promise of new beginnings fills the air as Baby and Johnny reconnect in a heartfelt dance that resonates with the audience and the essence of change.
