Mika is a conflicted teenager struggling to cope with the loss of her mother and the recent marriage of her father to Sheryl. In her search for solace, she decides to visit Mount Milagros in Batangas, a cherished hiking destination frequented by her and her mother, while secretly hoping for an alien abduction to take her away from her pain. During her journey, an unexpected encounter occurs when she accidentally runs over the foot of Caloy, a young man biking to Calaca to reconcile with his father. Despite her initial fear, believing him to be dangerous, Mika decides to help him out of guilt.
As they travel together, both Mika and Caloy share their personal stories, revealing Caloy's battle with leukemia and his current state of remission. The conversation takes a light-hearted turn when they debate the diet of carabaos, leading them to seek help from Berting, a local farmer. However, Berting reprimands them for their arguments and continues on his way, leaving Mika to feel a tinge of compassion, prompting her to offer him a ride. Their journey encounters a hiccup as several chickens escape during the ride, which leads to a delay in reaching their destination. Upon arriving late, Mika steps in to defend Berting before his mother-in-law, gaining respect from everyone involved.
In a whimsical turn, Mika and Caloy discover one of Berting’s chickens hiding in her car and affectionately name her Goldie. They continue their adventure, pretending to be a married couple, which lightens the mood during their trip. Their cheerful day includes a lunch stop with Aling Berns and her daughter Ronnabel, who later finds herself in a tense situation at her high school prom due to anxiety over a crush. Encouraged by Mika and Caloy, Ronnabel gathers the courage to face her fears and attend the prom, joining the group in their lighthearted escapades.
However, their journey takes a more serious turn when they arrive at Caloy's father’s place, only to be met with rejection. Frustrated and despondent, Caloy contemplates taking drastic measures at a nearby bridge, sharing his fears of cancer returning with Mika. In a pivotal moment, Mika convinces him to join her at Mount Milagros, where they hope to seek their fate among the stars. Along their path, they are reunited with Ronnabel, who decides to join them for further adventures.
Navigating through some detours, they manage to book a hotel for the night, allowing Mika to resolve some family tension over a phone call. The next day, however, tragedy strikes when Mika finds Caloy in a dire state, bleeding and weakened by his illness. Despite his protests against burdening others, Mika remains insistent, helping him reach a hospital, supported by his family during a critical time. While undergoing treatment, Caloy experiences a vivid vision of both him and Mika being abducted by aliens atop Mount Milagros. Once awake, he learns of Mika’s selfless act: raising funds for his treatment alongside Goldie and leaving him a heartfelt letter expressing that he gave her hope to live.
Eventually, Caloy makes a full recovery and finds himself drawn back to Mount Milagros. At the summit, the weight of their shared experiences leads to an emotional reunion with Mika, signifying hope, healing, and the strength of newfound bond forged in the face of adversity.
