Koi... Mil Gaya2003

Years ago Dr Sanjay Mehra built a computer to signal life beyond Earth. Something answered, and he was killed in a crash the same night. His son Rohit survived it and grew up with the mind of a child.

Rohit lives with his mother Sonia and spends his days among the local children, who accept him. Nisha, newly arrived in the town, does the same, which is more than Raj and his friends manage.

When Rohit finds his father's old computer and sends the signal again, a craft comes and leaves one of its own behind. The children name him Jadoo, and Jadoo begins changing what Rohit can do.
