Kantimathi

A truly great film, Pathinaru Vayathinile (or 16 Vayathinile) is about the vulnerability of a woman, and yet her strength: at the same time, she can change the life of a man through her love, and she can mar her own life by falling for the wrong man in the first place. (dearcinema.com)

Rajamani (Nasser) and his twin sons, Vishu and Ramu (both played by Prashanth), live in America. When Vishu falls for the beautiful Madhumita (Aishwarya Rai), his father insists that his boys also marry twins. Madhumita's response is to pose as her imaginary twin, Vaishnavi. The charade works too well when Ramu decides he wants to be with Vaishnavi. Now, Madhumita must reveal the twisted truth before she ends up married to both brothers. (Netflix)
