Claude, Alison Folland, is a tomboyish teenage girl living with her divorced mother in Hell's Kitchen, New York City, during summer vacation. The story centers on her sexual self-discovery and the early stages of lesbian feelings as she tries to figure out who she is, what she wants, and how to navigate friendships and desire in a neighborhood that feels both claustrophobic and alive. Her closest confidante is Ellen, Tara Subkoff, a charismatic friend who seems to understand Claude in a way no one else does. The two dream of forming a band together, a shared project that promises freedom and a space to express themselves, but that plan gets upended when Ellen begins dating Mark, Cole Hauser, a guitarist who appears to offer something more exciting and dangerous at the same time.
Beyond the apartment building, Claude’s world becomes heavier when she learns that Luke, Pat Briggs, a gay musician who has just moved into the same building, has been stabbed to death in what might have been a hate crime. Ellen suggests she was present at the time of Luke’s death, but Claude chooses silence to protect her friend. The unease of Luke’s death hangs over the summer as Claude slips away from her old routines and ventures into unfamiliar spaces. She ventures into a gay bar and meets Lucy, Leisha Hailey, a pink-haired guitarist who is part of the house band, and their paths cross in a way that pulls Claude toward a new, soulful attraction.
At Lucy’s apartment, Claude and Lucy begin to share a tender, tentative romance, but Claude’s emotions spike and she retreats, only to return home to find Ellen waiting for her. The two exchange a tense confrontation in which Claude is forced to confront how much she needs Ellen, and Ellen’s dependence is laid bare when Claude reveals how deeply she cares—even if that care is tangled and perilous. Their feud intensifies when Claude hears that Ellen has been protecting Mark, and a painful moment arrives when Claude lashes out, declaring that she would die without Ellen. The moment crystallizes their fragile bond, revealing how closely love and risk are braided together for both of them.
Soon they accompany Mark on a date, during which Mark serves Ellen downers that leave her violently ill. Claude helps, guiding Ellen to the bathroom and insisting she vomits, a scene that underscores the complexity of their relationship and the power dynamics at play. Ellen calls Claude her “Knight in Shining Armor,” a nickname that feels both affectionate and suffocating in the moment. Claude’s anger at Mark swells beneath the surface, yet he remains outwardly composed, a protector on the surface who might still be dangerous underneath.
Claude decides she cannot stay silent about what she suspects Mark might have done, and she returns to Lucy’s world with a renewed sense of purpose. On the way home from that night’s events, Mark corners Claude and questions her involvement with Ellen, threatening to expose any knowledge she might have about Luke’s death. Claude, driven by fear for Ellen and a sense of justice, threatens to go to the police with what she knows about Mark, hoping to uncover the truth and spare Ellen from further harm.
Back home, Claude confronts Ellen with the plan to report Mark, but Ellen reveals a chilling loyalty to Mark that would land them both in trouble. The tension explodes into confession and heartbreak as Claude tries to sort out loyalty, love, and safety. Ellen insists she would not go to jail for what might have happened, and Claude, determined to protect herself and others, resolves to tell the authorities. The moment culminates in a kiss that marks a definitive turning point: Claude tells Ellen she loves her, while Ellen cautions her not to voice such feelings out loud, insisting she isn’t ready for that kind of romance.
The next day, Claude begins to reclaim her personal space—clearing out the remnants of her relationship with Ellen and stepping back into her own life. She goes to the police before starting her shift at work, a decision that results in Mark being brought in for questioning. The news of Mark’s involvement shocks Ellen, who hates Claude for “rattling” him out, and their friendship fractures beyond repair. In the wake of the upheaval, Claude cautiously moves forward, beginning to see Lucy more openly and planning their first date, signaling a hopeful but uncertain new chapter in her summer of self-discovery.
Throughout, the city’s heat and the claustrophobic summer ignition push Claude toward choices that redefine who she is, who she loves, and how far she is willing to go to protect herself and those she cares about. The film paints a careful, intimate portrait of adolescence, desire, and risk, balancing moments of tenderness with the sharper edges of confession, loyalty, and the consequences of speaking truth to power.
