One would wonder what is in store for movie buffs after seeing movies like Murder, Hawas, Julie, Girlfriend… having loads of steamy content for the audience right from plain lust, prostitution to lesbianism and not to forget Abbas-Mustan’s theme of wife-swapping in ‘Ajnabee’. This time around director Sunjay S Zaveri has a unique offering of ‘Husband Swapping’ (yes you read it right). The cast is red hot with Payal Rohatgi (Tauba-Tauba fame) shedding more and more from ‘Yeh Kya Ho Raha Hai’ to ‘Tauba Tauba’, guess what you can see now!! Heena Rehman (debut film I-Proud To be An Indian with Sohail Khan), Aryan Vaid, Siddharth Koirala (Manisha Koirala’s brother finally making his debut)
Fun – Can be Dangerous Sometimes is about Natasha, Phalguni and Urmila, three married women who believe ‘you live only once and one should enjoy life fully’. However Phalguni and Urmila feel their respective marriages lack excitement and have become stale. On the other hand Natasha has no such complaints against her husband Aryan.
But strangely enough Natasha suggests that the trio should swap husbands and have some fun. Initially Urmila and Phalguni are shocked by the suggestion but when Natasha explains her plan the two agree to have fun.
The plan is hatched – while the husbands are clue less. The three couples head out to a resort to bring in the New Year. The plan begins, the three women draw lots (whose husband falls is whose laps) and as luck would have it Natasha is left with her own husband. Meanwhile Phalguni and Urmila go all out to seduce each other's husbands.
During their stay, the trio comes across Meghna. Aryan finds himself getting attracted to the new comer and Natasha encourages this relationship and pretends she doesn't care.
Meghna however is married to a wealthy man Raj with whom she shares a strained relationship. As the 31st of December approaches, strange things begin happening. Meghna begins receiving anonymous messages from a person who claims to be her lover while Raj starts getting threatening calls. And it only gets worse.
On New Year's Eve Meghna is found dead in the resort's swimming pool. Meghna was last spotted with Aryan. He is the prime suspect, but is he the real culprit? Or a part of a well planned conspiracy.
