Wealthy businessman Jiang Hao is celebrating his success aboard a luxury cruise ship when he accidentally falls into the sea and travels back in time to 1998, inhabiting the body of another man with the same name.

He even stole his daughter's life-saving money to gamble. Determined to make the best of his second chance, Jiang Hao uses his extraordinary abilities to earn money step by step and establish himself in the rapidly changing era. Not only does he regain the trust of his wife and children, but he also earns the respect of the entire village and leads everyone toward prosperity.
