The rule: Get married and have a baby.

When Grandpa Stinson dies, he expects nothing more than to keep his grandsons together, running the family's multibillion-dollar business. But he's got just one unfaltering rule: they have to get married and have a baby first. The brothers disagree...wholeheartedly.

But it's set in stone.

Follow the rule or you're one grandson out of luck...

Loving a good challenge, playboy bachelor, TJ Stinson decides to take the bull by the horns and puts out an ad in the local newspaper for a wife and "baby mama." Determined to get the job done, TJ interviews women, making sure this is in contract only--no ties of love for this particular agreement.

Overhearing one of his ridiculous interviews, Anna Granger decides she'd be perfect for the "role." But what happens when neither of them are pretending anymore? Their pasts have a way of creeping back up on them, teaching them what Grandpa Stinson knew all along: there's more to life than just prestige and money.
