Felicity and Sara came to Las Vegas to celebrate best friend and bride-to-be Laurel. What they hadn’t planned on was Laurel’s fiance guilting her into bringing his troublesome sister Thea. Thea, who decided to make things a little “extra fun” and drugged them all, giving them a night they’ll never remember.
Not only did they lose Laurel, and wake up in a trashed hotel room with Sara missing a tooth, but Thea found a baby and there’s a ring on Felicity’s finger.
Through a series of mishaps the women retrace their intoxicated steps, find Felicity’s stripper husband, Oliver (and return his baby), before they finally locate Laurel on the roof of their hotel.
The ladies manage to get back just in time for the wedding rehearsal, the bride a little sunburnt, and all agree to never speak of what just happened in Vegas.
