Aayushkalam is based on the Hollywood films Ghost and Heart Condition and was in turn remade in Hindi as Hello Brother.

Surprisingly and luckily he receives the heart of Aby Mathew, a youth who has died in a car accident.

Balakrishnan tries various methods to drive Aby's ghost out of the house, but all fail and makes everyone believe he has gone crazy.

Aby tells Balakrishnan that he was in fact murdered very unexpectedly on a busy road, by a man whom he could not identify, initially using a gun, but he was later run over by the vehicle while he was leaving to see his newborn child.

Damu causes significant hilarity at this point, especially because he appears foolish and naive but shows off as though he is a wise and experienced policeman.

With the help of Damu, Balakrishnan discovers that Aby was murdered by a notorious criminal named Benjamin Bruno.

Aby sees Alex, his adopted brother, talking to Bruno about his murder and that it needs to be covered up.

The film proceeds to the next scene where Damu refuses to help them anymore, as he fears he could get transferred anytime for believing in ghosts.
