While fishing, Lin Zhe accidentally discovers a mysterious communication device and encounters his future self from five years ahead. He learns that a major national project is about to be launched in the mountains behind Heishi Town. Seizing his only 48-hour window of opportunity, he decisively sells his property and beloved car to raise enough money to secure the land-use rights to 10,000 mu of barren mountains. His fiancée and future mother-in-law mistakenly believe he is drowning in debt and publicly turn against him, calling off the engagement. After investing everything he owns to complete the land transfer, Lin Zhe is left penniless, with an uncertain future ahead. All he can do is wait for the opportunity to arrive and watch his destiny turn around.
