Delivery driver Brian saved $1,086.42 for girlfriend Jessica, but she and her mother dumped him for being poor. While saving a girl named Emily, he is hit by a car. His deed moves the mysterious old man Elias, who devalues all global currency a hundred-million-fold—except Brian's savings, making him the world's richest man overnight. Unaware, Brian lives as an ordinary man, while former richest man Edward and three great families search for him; Emily, secretly Edward's granddaughter, is the girl he saved. At a tycoon banquet, Jessica and her new boyfriend Derek mock Brian and try to cripple his hands—until Edward and the family heads arrive, confirming Brian is the new global richest man and exposing Derek. Brian still lives in a tiny rented room, folding dollars into paper cranes; when landlady Vivian sees a ten-dollar crane he gives away, she waives his rent and plans to introduce him to her cousin, streamer Chloe. His life as the richest man begins.
