Shen Chuan takes over operating the Old Times Internet Cafe for more than twenty years, facing rent arrears, debts, aging machines, and the step-by-step pressing of the chain giant Polar Day. Just as he prepares to sell the shop, childhood playmates Jiang Ye, Zhou Yue, Gu Yan, and Tang Ning return, each showing their strengths to help him reorganize and rebuild. Shen Chuan grows from initially only wanting to last three months into an independent operator. Facing Polar Day's sky-high acquisition offer, he resolutely refuses. In the end, Old Times glows with renewed vitality, the whole old street's fireworks burn brighter, and Polar Day also leaves with dignity.
