Rajaratham is the name of a luxury bus that is on its way from Hyderabad to Bengaluru.  Its voice (Rana Daggubati) introduces the audience to its very many oddball or troubled passengers.

Abhishek (Nirup Bhandari) and Megha (Avantika Shetty), the collegemates, are two of them.  They end up sitting next to each other in the bus.  It's Abhi's chance to impress his crush, who herself has had a not-so-pleasant relationship with her lover.

Vishwa (Tamil actor Arya) is a henchman who works for a politician out to provoke clashes between the Telugus and the Kannadigas over an unfavorable Supreme Court verdict.  Even as this drama builds up, Abhi and Megha continue to bond over unforeseen situations.

But then, as fate would have it, Rajaratham itself will have to witness a tragedy as politics of hate strikes at its 'heart'.  But not the spirit, as we shall soon see.
