However, when Phil, Stu, and Alan awaken, Doug is gone and they have no recollection of what happened the night before. They have to find the groom before the wedding can go place.


Doug Billings, a happy but cautious bachelor, takes a trip to Las Vegas with his closest pals Phil Wenneck, an ironic elementary school teacher, Stu Price, a nervous dentist, and Alan Garner, his peculiar future in-law. 

However, Sid, the father of Doug’s fiancée Tracy, gives Doug permission to travel to Las Vegas in his antique Mercedes-Benz W111. When they are given a suite at Caesars Palace, they sneak up to the rooftop bar to celebrate by drinking Jägermeister. 

Phil, Stu, and Alan wake up the following morning with no recollection of the previous evening. Also, The suite is a mess, Stu’s tooth is missing, Doug is nowhere to be found, there’s a Bengal tiger in the bathtub, and a baby is in the closet.

When they ask the valet for their Mercedes, he or she brings them a cruiser from the Las Vegas Metropolitan Police Department. Outside, they observe Doug’s mattress pinned to a monument.

Retracing their ways, the group arrives at a hospital where they learn that Rohypnol was used to cause them to lose their memories and that they had come from a church the night before.

At the church, they find out that Stu wed Jade, a call girl, while having a relationship with his controlling and philandering Melissa. Gangsters outside the church attack the group and demand to know where “he” is. They run away in confusion and find Jade, the mother of the child.

Because they stole the vehicle, the cops detain them. The trio, who had been informed that the Mercedes had been seized, are freed when they unintentionally agree to be the targets of a taser demonstration.

 Leslie Chow, a nude Chinese guy, who is in the Mercedes trunk, hits the group with a crowbar as they are driving, and then he runs away. Alan admits that he spiked their drinks, thinking it was Ecstasy, to make sure they had a nice time.

They encounter Mike Tyson when they get back to their suite, who knocks Alan out and tells them to bring his tiger back to his mansion. They load it into the Mercedes and head to Tyson’s estate after Stu drugs it.

But as the tiger wakes up, he charges at them, clawing Phil on the neck and wrecking the interior of the car. Furthermore, The remaining distance to the mansion is pushed by them as they present the tiger to Tyson. 

Tyson then plays security camera video to them, proving that they did not lose Doug until they returned to the hotel. Their automobile is struck by a black Cadillac Escalade driven by the gangsters from the chapel and their leader Chow as they are returning home. 

In addition to kidnapping him, Chow claims they stole $80,000 worth of poker chips. He claims to have Doug and, when they deny having it, makes a death threat on Doug. With assistance from Stu and Jade, Alan utilises his card counting skills to play blackjack and earn $82,400 without being able to discover Chow’s chips. 


They trade the chips for Doug when they meet Chow in the Mojave Desert, only to discover that Doug is actually the drug dealer who sold Alan the roofies. In the five hours before the actual Doug’s wedding, Phil phones Tracy to let her know they haven’t been able to locate him.

Stu is alerted to Doug’s whereabouts by the other Doug’s statement that someone who uses roofies is more likely to land on the floor than on the roof. Back at Caesars Palace, they discover a confused and sunburned Doug on the roof. 

As a practical joke, they brought him there on his mattress, but when the roofies wore off, they forgot. Doug tossed the mattress at the statue in an effort to get assistance.

Stu schedules a date with Jade for the following week before departing. Without any flights, the four take the wrecked Mercedes home, where Doug reveals that he still has Chow’s initial $80,000 in his pocket.

Doug and Tracy are wed despite their tardiness. However, Stu yells at Melissa and separates them at the wedding. The four decide to see the images before deleting them after Alan discovers Stu’s digital camera on his person. The camera had shots of the revelry from the night in Las Vegas.
