Billionaire Sir Guy Grand (Peter Sellers) thinks nothing of throwing his endless stream of money away. He adopts a street person (Ringo Starr), christens him Youngman Grand and sets about trying to illustrate to his new heir how virtually everyone in the world can be bought. He pays a traffic cop to eat a ticket, pays the Oxford crew team to sabotage a race and finally fills a vat with feces and money, inviting one and all to keep the latter if they don't mind putting up with the former.
