What is the shelf-life of our Karma? Is it possible to escape from the fruits of our Karma ever? Can a meticulously built character be marred by a sin committed in the past?

Welcome to The Last Evidence.

Ramgopal, a tourist guide in New Delhi, often engages in interesting conversations with his tourists, impressing them with his vast knowledge on various subjects. However, by sheer coincidence, all the tourist's houses are burgled before they reach home after the tour.

As the investigation progresses, the needle of suspicion points towards Ramgopal. He flees the city and takes shelter in a remote ashram to avoid being caught. Gradually, he transforms the entire region and earns the trust and respect of the villagers.

When he is about to be rewarded by the local administration for his significant contribution to the all-round development of the village, the old investigation reaches his doorstep. Will the law catch up with him? Will he be exonerated? Is he really guilty?
