Unexpected Help

Rahul was skeptical to go to school. He starts crying and creates a ruckus in the morning. His parents are worried. They don't know the reason for his skepticism. Rahul and his family have moved to Noida only this year from Chennai. South to North is a big move for him. He gets teased at school for his accent and lack of understanding of the Hindi language.

Prince, his classmate is the main person behind all of this. He and his friend's group has made it a purpose to tease Rahul every day. Tearfully, he explains his problem to his parents. They do understand but tell him that all of this is a part of growing up and that things will settle down on its own.

His father, a great scientist is busy working on different missions to space and has now been transferred to North to fix some Government related issues at Delhi.

His computer with all the signals is always on and it so happened that the aliens in space have been hearing all that's going on at their home. Jadoo, a kind alien decides to come to Earth and help Rahul overcome his shortcomings. But there is an issue there. His brother, PK cannot stay a single day without him, they being closest twins. PK is ready to accompany Jadoo on his mission. But the leader of the Alien Group advises against the idea. He is of the opinion that only one alien can safely survive in a particular place on Earth as the humans on Earth are really crude people who don't respect people or nature. They don't understand the blessings they are surrounded by and always take everything for granted. The leader explains that these humans respect fake Godmen more than their own clan of people. What strange behavior they have. They don't understand that nature is the true God and not the fake men who proclaim so.

So, after a huge discussion by the Alien Committee, it is decided that Jadoo and PK will get to Earth on different missions. Jadoo to Noida to help Rahul overcome his problems and PK to Bangalore through Rahul's father's other computer to Bangalore to study human nature.

But they have to go together and be back together.

And so, one fine day, Jadoo lands in Rahul's school at Noida as a human boy, another new boy who joins the school. He uses his special powers and accent to attract all the kids at the school. At the same time, he develops a special friendship with Rahul.

Slowly but surely, Jadoo works his magic on everyone. Seeing him become Rahul's closest friend who gets access to all his secrets, Prince slowly learns to accept Rahul for what he is and stops teasing him.

And therein Bangalore, PK in human girl form was busy engaged. He has befriended a girl in an NGO that works with preserving nature in all its beauty. PK works with full dedication to the cause. In due course of time, he/she questions people around on the acts they do every day that lead to the downfall of nature. People are educated by PK and his team on things like waste disposal, plastic use, and ban, use of crackers, cutting of trees, using eco-friendly products, etc... The NGO also trains the public on making their own compost at home and growing their own vegetables. Slowly PK's company grows and people get educated with more and more people joining it.

As of this action was closely monitored by the Alien Group in space. They were glad that they could contribute and help the humans on Earth. When the leader realized that both PK and Jadoo have done their jobs successfully, he sends them a signal through a transmitter that it's time for them to get back home.

On the designated date, both PK and Jadoo get on to their spaceship with a heavy heart as they had grown accustomed to being around humans. They had also developed a strong attachment to things and people. As a souvenir, they took back things from Earth.
