Once

Core Plot: Dual Pursuit of Musical Dreams and Life Values

Main Line One: The Struggle of Street Musicians
Wang Yiming, a young man from a humble background, is inspired by his parents' love for music. Despite lacking the financial means for professional training, he self-learns guitar and composition through online tutorials. The story intricately depicts his real-life scenes of working to fund equipment, gaining experience through street performances, and forming the "Rooftop Band," connecting with drummer A-Kai and keyboardist Xiaomin, showcasing the spirit of mutual support in the grassroots music scene.

Main Line Two: Emotional Resonance from an Unexpected Encounter
Xu Wenwen, facing setbacks in her career, fortuitously steps into Wang Yiming's small bar performance. They resonate with each other through the original song "Night Light." The narrative unfolds through events like "improvised jam sessions at the subway station" and "renovating an old music store," illustrating their evolution from musical partners to lifelong friends. The scene where they create percussion instruments from drink bottles vividly demonstrates artistic creativity amidst resource scarcity.

Production Features: Authentic Foundation in Realism

According to interviews with the writers, the script is based on real cases of street performers on Yulin Road in Chengdu:

Character prototypes include an independent band leader who once set up stalls to gather resources for a music festival.

Details like "modifying takeout boxes for sound equipment" and "trading for effects pedals in second-hand markets" were informed by field research.

The music director invited the live sound team from "The Big Band" to assist with design.

Core Insight: Multiple Paths to Dream Realization

The film breaks the stereotype that "fame equals success," focusing on:

How public performances in community squares reignite the musical passion of retired seniors.

The original song "Streetlights and Stars" becoming a rallying cry for delivery workers' morning meetings.

The community music classroom created from the old music store, providing free lessons for underprivileged children.

Social Resonance and Educational Significance

The early-released behind-the-scenes footage of the "Rooftop Concert" was shared by the Chinese Musicians Association, and Sichuan Normal University has included the film's plot about "music therapy for depression patients" in their art therapy course case studies. Although the release date and cast have not yet been announced, the heartfelt and genuine script foundation has already generated fan anticipation.
