The Hangover

 A man called Doug drives to Las Vegas for a Bachelor party with friends Alan, Stu and Phil. Doug goes missing, there’s a tiger in the bathroom and a baby in the wardrobe, and Phil has a hospital tag on his wrist. Its all in an extended flashback from drinking a toast to waking next day with no memory of the night before. Turns out the men were drugged with ‘Roofies’. Stu they discover is married to a stripper Jade, mother of the baby. The police are involved and find their stolen car and arrest the guys for theft only to release them for helping to demonstrate stun guns to school children. They go and find their own car and in the boot there’s a naked Chinese man who attacks them and runs away. While another Chinese man hands over an other man called Doug who turns out to be the dealer that supplied the ‘Roofies’ - and there you have it.
