The film centers on Heidi, a teenager residing in suburbia Canberra, who decides to run away after making an unexpected and bold sexual advance towards her mother's boyfriend. In her quest for escape and freedom, she flees to a ski town nestled within the Snowy Mountains, hoping to reunite with a man who once offered her assistance. However, upon reaching out to him, she is met with rejection when his wife answers the phone, and he denies ever knowing her. Left feeling isolated and lost, Heidi navigates through various bars and shops in search of support, but it appears no one is willing to help—until she meets Joe, a young man who takes notice of her, buys her a drink, and extends a kind offer of a place to rest.
As the morning dawns, Joe leaves for work, and Heidi finds herself befriending Irene, the stern yet compassionate motel manager. Irene allows her to stay temporarily and even helps her transition into her son’s empty flat. In an effort to support herself, Heidi secures a job at a petrol station and begins to carve out a delicate daily routine. Fate intertwines their lives again as Joe reappears, and although their connection is rekindled, it remains somewhat turbulent. During this time, Heidi also forms a friendship with her co-worker Bianca, who brings a sense of warmth and camaraderie into her life.
As the relationship between Joe and Heidi develops into dating, the stability of their bond is continually tested. When Joe's friends make light of Heidi's job, she feels a wave of humiliation wash over her. While sharing a dinner, her need for emotional reassurance surfaces as she probes Joe about his feelings towards her. His prolonged silence prompts a distressing reaction, leading her to consume a large bowl of hot chilies in frustration. Joe jumps into action to help her, but later he finds solace in alcohol at a gathering, where an unexpected moment occurs when he kisses his neighbor Richard—a gentle confrontation that forces Joe to grapple with his own self-awareness. The next day, he returns home to an emotional breakdown in front of his father, whose own emotional distance adds to Joe’s struggles.
While all this unfolds, Heidi uncovers a shocking truth; Bianca's father is none other than the man she previously attempted to seduce. After a ride home with him, she receives a stern warning to stay away from Bianca. The following day, tension escalates as Bianca confronts Heidi, prompting her to quit her job in a fit of anger. That night, overwhelmed by the day's events, Heidi seeks escape at a nightclub where her decision leads her to bring two men back to her place. Her situation turns dangerous when one of the men begins to strip and prepare to assault her, but in a dramatic turn of events, Joe arrives just in time to thwart the attack. His subsequent expression of anger towards her risky behavior, paired with Heidi's accusations of his indifference, culminates in him leaving her at the motel, emotionally distant yet unresolved.
The next day, Irene asks Heidi to vacate the premises. The two share a poignant exchange in which Heidi finally admits her mother is alive, and Irene reveals the painful truth that her own son is incarcerated for murder. With great empathy, Irene encourages Heidi to mend her relationship with her mother. Later that day, Joe returns, only to find Heidi in the midst of packing. As they wait in suspense for her mother's arrival, Joe finally reaches out and holds her hand. When her mother finally arrives, Joe attempts to steal a kiss goodbye, but Heidi stops him. She simply expresses that she is happy they met before leaving with her mother, allowing the snowy scenery to fade into the background as the film draws to a close.
