The death of a successful industrialist tests the skill and patience of ACP Malvika Chauhan (Sushmita Sen), a celebrated officer and an idol to many a woman in the country.
ACP Malvika Chauhan starts to do what she is best at - solving difficult crimes. This investigation - the biggest challenge she has faced till now in her career - is a journey so dark and daring that she did not know it existed.
The murder prima facie is strange as there seems to be no clue or motive of any kind that could form the basis of the crime. The investigation leads to some inexplicable clues including the stab wound on the neck of the victim. The post-mortem rules out any foreign particles in the blood - a fact that defies logic. ACP Malvika finds herself up against a wall.
Till she spots the one crack in the case.
As she gets deeper and deeper into the investigation, she realises the murder to be the handiwork of a genius - a criminal mind that has left everyone stunned with its brilliant execution.
ACP Malvika, with other circumstantial leads and her sharp observation skills, builds the puzzle piece by piece. But only to provide a solution that she herself does not believe in.
What role does time play in the battle of the great minds? Will the ACP get to the bottom of the crack? Or is the crack just an illusion?
