A poor and amateur writer named Tarak Chatterjee approaches the nameless Editor of Sandesh with a journal by Professor Shonku (a scientist who had disappeared 15 years ago).

Later he found several alien plants growing in his yard which, if blown in the air, appear to wave at him as if calling him somewhere.

His neighbour, Abinash Chandra Majumdar, teases him because of his wish to travel to space, but he turns a deaf ear to him.

After finally creating the spaceship, Shonku, his domestic worker Prahlad, his pet cat Newton, and his robot Bidhushekar, travel to space.

When the spaceship enters in Mars, Bidhushekhar is switched on, but the robot, afraid due to an unknown reason, refuses to go out.

Perplexed, Shonku discovers that the controls aren't working and no proper destination is fixed; he's indescribably horrified.

A few days later, Shonku and Prahlad, upon the insistence of the revived Bidhushekhar, discover that the spaceship is flying through huge unexplained bubbles which are expanding and exploding on their own accord.

After crossing all these things, the spaceship arrives at Tafa, an unknown planet which, according to Bidhushekhar, is "inhabited by the first civilised people of the Solar System".

After copying the aforementioned part of Shonku's story, the Editor returns home from work one day, only to find out that the journal has been destroyed by a swarm of fire ants.
