The movie start with Malabar during the mid-1920s after the fall of Ottoman Empire and Khilafat in Turkey. In 1921, the Malabar Muslims, known as Moplahs, started a rebellion against the British raj that they treated as enemies of Islam. The British suppressed the agitation of Moplah Muslims in connivance with the Hindu landlords and deported some leaders of the rebellion to Andaman Islands.
In mid of August 1921, agrarian riots broke out in Nilambur. The Moplah peasants revolted against the Hindu landlord's oppressive policies, which are in alliance with the British. The Hindu landlords redistributed their lands and the Moplahs, who had been suffering, rose in revolt. A pitched battle between the British regiment and the Moplahs killed several Europeans. Four thousand Moplahs were killed in action and tens of thousands were injured.
Then there was the notorious Moplah Train Tragedy. Around a hundred prisoners, confined in a closed and almost airtight goods van, were transported by rail. When the door was opened, 66 Moplahs were found suffocated to death and the remaining 34 were on the verge of collapse.
