Naughty @ 40

Happy (Govinda) is a 40 year old man living in London with his parents (Anupam Kher, Smita Jaykar). He's still a virgin and sleepwalks in the nights. Happy's father seeks the help of his employee (Shakti Kapoor) and his nephews to help Happy lose his virginity, but all efforts turn futile.
　　The family leaves for Manali, where Happy gets married to Gauri (Yuvika Chaudhary), a girl much younger to him. However, Gauri is up to childish pranks all the while, which results in Happy getting into a physical relationship with a London based model who is in the town for photo shoot. When Gauri discovers the truth, she gets a rude shock. That brings about a change in her attitude. wiki
