Money Hai Toh Honey Hai (2008)

It's a hilarious storey about six people who are in no way connected to one another. They receive an SMS one day that informs them that they are the owners of a 1000 crore business. Their joy is short-lived, though, when it is revealed that the company has a 1200 cr debt to repay. Nonetheless, they will be put under house arrest before the debt was repaid.
