Rajkumar's brother, the king, died from a mysterious illness, plunging the kingdom into chaos. Rajkumar fled, unable to bear the responsibilities. He built a new life in another kingdom, running a successful hotel. Six months later, Rajkumar returned to find his kingdom under the tyrant Raghav, who falsely accused him of treason. Reuniting with allies, Rajkumar gathered evidence and incited a revolt.
In the final confrontation, he poisoned Raghav and reclaimed the throne. Rajkumar vowed to restore the kingdom's glory, ruling justly and fulfilling his brother's legacy.
