For charismatic party guy Jack Fuller and buttoned-up commodities trader Joy McNally, a rowdy weekend coincidentally shared in Las Vegas should have ended up being little more than a random blur. That is, if these two vacationing New Yorkers didn't have a signed marriage license to shockingly remind them of the giant misstep they took while feeling no pain, Vegas-style. Not only did Jack and Joy tie the knot after tying one on, but later scored a mind-blowing three 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. Otherwise, the judge guarantees, the three million bucks will stay caught up in a legal battle so long and expensive no one but the lawyers will ever see a penny of it. Jack and Joy figure, "Fine, how hard can it be" and take the bait only to find themselves locked in a patience-testing, panties-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 first--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 astonishingly real?
