Urchagam is a love story of Jency (Sherin) and Ganesh (Nandha), which deals with dilemmas and difficulties arising in love marriage and arranged marriage.
Jency is engaged to Nicholas (Dinesh Lamba) who is rich entrepreneur in London. He saved her mother's life and to repay his debt, she decides to marry him. However, being with a jealous and protective lad like Nicholas turns her life miserable and then Ganesh comes to her rescue, when he goes against Nicholas for Jency.
How they unite, whether or not, forms is that what remains to be seen.
