India, May 1 -- Patriot plot: Daniel James, a Defence Research Wing operative, is driven into exile after uncovering a surveillance conspiracy involving the defence minister and his son's tech firm. But exile doesn't stop his pursuit of the truth and it leads him to an even deadlier conspiracy, which will force him back to the country and could prove fatal for him and his aides.

Be it Take Off, C U Soon or Ariyippu - each distinct in their filmmaking, his storytelling has consistently been anchored in solid, idea-driven material.
