Thank You (2011)
Raj (Bobby Deol), Yogi (Suniel Shetty) and Vikram (Irrfan Khan) are best friends and business partners who are married to Sanjana (Sonam Kapoor), Maya (Celina Jaitley), and Shivani (Rimi Sen), respectively. What their wives don't know is that their husbands cheat on them often with not one, but many women.
Yogi has already been caught by Maya after the latter hired her new-found friend Kishan (Akshay Kumar), a private detective, to check on Yogi. Now Yogi's status in the marriage is reduced to that of a butler at home. Yet Yogi still has aspirations for more hanky panky if the right opportunity comes along.
Raj is in good shape, as Sanjana is quite gullible and suspects nothing. However, Sanjana finds out from Maya that the necklace that Raj had supposedly bought only for her actually was a buy one, get one free deal. So where is the other necklace? Shivani, Maya, and Sanjana all get together, and Mala decides to hire Kishan to tail Raj.
