In the neon‑lit streets of 1990s Hong Kong, two young art students—Xu Lai and Yang Yi—forge a passionate romance that feels as vibrant and fleeting as the city’s ever‑changing skyline. Their love, intense enough to scar memories decades later, is interrupted by an abrupt move that carries Yang Yi across the harbor to a prestigious university, leaving Xu Lai to carry the echo of that first love long after the canvas has dried.
Fast forward twenty years, and Xu Lai now leads a comfortable, routine‑bound existence alongside his steady, supportive wife, Cai Bo. Though their life together is warm, a quiet ache persists, a reminder of the fire that once burned bright. When a family vacation beckons them to Hong Kong, the trip promises not only a change of scenery but also a tentative opportunity for Xu Lai to glance back at a chapter he thought was closed.
The journey unfolds amid a lively tapestry of relatives whose eccentricities and good‑natured meddling create both comic relief and subtle pressure. Among them, Cai Lala—the ever‑present younger brother armed with a camera—captures every moment, turning ordinary interactions into a surreal documentary of family dynamics. Adding an undercurrent of intrigue, two diligent police officers, Sam Lee and Eric Kot, linger in the background, their investigative instincts hinting at mysteries that quietly ripple through the bustling streets.
The film balances nostalgic yearning with a brisk, off‑beat humor, painting Hong Kong as a character in its own right—vivid, crowded, and brimming with possibilities.
