Kathirvelan, played by Kaushik Ram, is a young man who falls in love with Cristina (portrayed by Pratibha Pandiaraj) during a temple festival. To stay close to her, he gives up his dream of going abroad and joins her college. Cristina does not completely accept his love, but also does not push him away. Meanwhile, another couple from their college elopes for an inter-caste marriage, and Kathirvelan and Cristina sign as witnesses, unknowingly using their Aadhaar and ration cards in a way that would later change their lives.

As the story unfolds, Cristina’s family arranges her engagement to a Christian groom. However, a shocking truth comes to light when a priest discovers a marriage certificate declaring Cristina and Kathirvelan as husband and wife. It is revealed that corrupt officials have used the witness documents to register fake marriages. To resolve this, Cristina secretly visits the registrar’s office several times, causing her fiancé’s family to doubt her actions. The situation worsens when her family strongly opposes her involvement with a man from another faith, recalling her sister’s tragic past.

Director SJN Alex Pandian handles the sensitive theme of love, faith, and social prejudice with an emotional yet grounded approach. The writing effectively blends romance and drama, while N. R. Raghunanthan’s music adds emotional depth to key moments. Kaushik Ram delivers a sincere performance as the determined lover, and Pratibha Pandiaraj impresses with her restrained expressions, especially in emotional sequences. Supporting actors like Singam Puli, Aarul D. Shankar, and Kanja Karupu bring natural charm and balance to the narrative. Produced by R. Prabhakar Sthapathy, the film succeeds in portraying how a simple mistake leads to life-changing consequences, offering a message about trust and the societal barriers of faith and identity.
