Running away from home can't keep a couple together. A signed paper can't keep a couple together. Love can. While for most love relationships, marriage is the "goal", the fact remains that marriage is just a beginning...
Aditya (Vivek Oberoi), a young middle class boy, meets Suhani (Rani Mukerji), a medical student and falls head over heels for her. He pursues her relentlessly in the local trains of Mumbai. Suhani, brushes off Aditya's overtures, because she wants to become a successful doctor and do her parents proud. However, Aditya's persistance pays off and she finally accepts. But opposition from her parents forces the couple to part ways. The seperation is unbearable and they get married in secret. Once they are married, is where the real story begins. The bliss ends and reality sets in with misunderstandings and quarrels in tow. Where do the newlyweds go from here? Will Aditya and Suhani understand the true meaning of being a "Saathiya"?
Saathiya continues on, from where most movies end. In this film all stagse of love are explored - from the infatuation stage, "when a couple things they are in love" right through to "when a couple discovers the true meaning of love".

With composer AR Rahman and lyricist Gulzar collaborating on the score and Shah Rukh Khan lending stellar support, Mani Ratnam's longtime assistant Shaad Ali has every chance of establishing his solo credentials with this reworking of his mentor's Tamil hit, Alaipayuthey. Rani Mukerji stars as the dedicated Mumbai medical student whose life is transformed when she falls for fellow commuter Vivek Oberoi. But, no sooner are they married than capricious fate tears them apart and a heart-tugging journey begins. This is very much the polished article we've come to expect from producer Yash Chopra, but Ali doesn't yet possess Ratnam's directorial finesse.
