Description: For charismatic party guy Jack Fuller and buttoned-up commodities trader Joy McNally, a rowdy weekend coincidentally shared in Las Vegas should have, by all rights, ended up being little more than a random blur. That is, if these two vacationing New Yorkers didn't have a signed marriage license staring them in the face to shockingly remind them of the giant misstep they took while feeling no pain, Vegas style. Stacking the deck, not only did Jack and Joy tie the knot after tying one on, but later scored a mind-blowing 3 million bucks in a slot machine bonanza. Well, Jack won it, with Joy's quarter. At the machine she'd already been playing. Or was it the other way around? And whose loot is it, anyway? Therein lies the weird hand dealt this bickering duo, who take their predicament back to Manhattan only to be sentenced by the intractable Judge Whopper to "six months hard marriage." Despite the hapless protests of Jack's best friend and legal counsel Steve "Hater" Hader, Whopper refuses to grant Jack and Joy an annulment, freezes the prize booty, and forces the irresponsible couple to prove they have done everything humanly possible to make their impromptu marriage work. This includes cohabitation, weekly counseling sessions, and doing something the old-school Whopper believes Jack and Joy's "generation" hates to do: try. Otherwise, the judge guarantees, the 3 million bucks will stay caught up in a legal battle so long and expensive that no one but the lawyers will ever see a penny of it. Jack and Joy take the bait, only to find themselves locked in a hilarious, patience-testing, panty-twisting game of wild one-upmanship--may the best "pretend spouse" win. Can Jack and Joy survive their six months of "wedded bliss" without killing each other, and ultimately cash in for the big payoff? Or will the fiery sparks that ricochet between them actually ignite, turning a fake relationship into something real? In the end, What Happens in Vegas may prove the biggest surprise of all.
