Here’s a concise summary of the story of the 2010 Bollywood film Karthik Calling Karthik :
Karthik reconciles with Shonali, leaves his toxic job, and starts his own business. The final scene shows him looking at a ringing phone — but this time, he chooses not to answer. He smiles, walks away, finally free.
Desperate, Karthik traces the calls and discovers they’re coming from his own office landline — the phone he alone uses. The horrifying truth dawns: the voice is not a ghost or a prank. It’s a split personality — a manifestation of his own repressed anger, trauma, and intelligence. The “other Karthik” was born from the pain of his brother’s death and the years of being a doormat.
