^Devdas (Shahrukh Khan) and Paro (Aishwarya Rai) are childhood sweethearts and are most likely going to get married. However, drama happens between Devdas' mom and Paro's mom...splitting the two lovers. Paro gets wed to a rich older guy, but is still in love with Devdas (and forever will be ^^). Devdas is heartbroken and gets introduced to alcohol...which then becomes his best friend. His friend takes him to this brothel where he meets Chandrumaki (Madhuri Dixit), a prostitute who falls in love with Devdas.
That's my brief summary of it ^^
