After the tragic loss of his girlfriend, Ning Chen receives a mysterious system task: fulfill her final bucket list. His journey begins with a luxurious, solar-powered RV and a modest sum of travel funds, but the true challenge lies in the emotional weight of the road ahead. Ignoring his grief, Ning Chen sets off on a solitary cross-country drive, aiming to reach a specific coastal destination within four days to witness a predicted meteor shower—a promise he made to her.

Unbeknownst to him, his silent, intense journey is being live-streamed to the world. Initially dismissed as a gimmick by a handful of viewers, his record-breaking non-stop driving marathon soon captures the attention of the nation. As the famous variety show 'Mushroom House' prepares to feature new guests, Ning Chen's private pilgrimage threatens to become public spectacle.

With only a dusty guitar and memories for company, he must navigate the physical exhaustion of the road while the world watches, slowly uncovering the touching truth behind his desperate race against time.
