I don't remember the story of *Ghayal* but this one is pretty unrealistic at number of times.
Ajay Mehra is the angry young( or old) man. A journalist - jo hamesha sach ke liye ladta hai - also running a cyber hacking network at a secret adda. *Dekh ke to bas Sony CID ka qtiyapa yaad aa gaya. * Yep you guessed it right, he keeps tracking on popular personalities with his superficial network. *for good causes ofcourse. * This secret is exposed towards the end but he still ends as a hero.
Four kids have some evidence against Raj's son, yeah the villain's son and while Raj is tracking them, Ajay too is tracking them. He finally took them in custody but finds them being kidnapped at the hospital.
While others are released one girl is still in their custody. Ajay hijacks villain's helicopter and lands it on his mansion.
A journalist knows how to fly a helicopter! Brilliant!
Then history repeats itself. *The one man army destroys the badman's entire kingdom.
