Based on a series of true events surrounding the gangster
Gampaha Osmond, between 1976 and 1991.
Set in the Gampaha district during a turbulent era of political
upheaval, Father follows Desmond Gunasekara — a deeply
religious young man from an ordinary family, preparing to leave
his village for police training.
His life turns on a single act of violence. Provoked by a thug
working for the local gang leader Gnane, Desmond strikes back, and
the prison sentence that follows strips away the quiet future he
had planned. Released and permanently marked, he is hunted by a
gang boss who cannot afford a rival — and then by the state itself,
once Gnane's political patron turns police power against him.
Desmond survives by becoming the thing he was running from. He kills
Gnane and flees to Japan; the retaliation falls instead on the
families left behind, and on his only brother. The film ends not in
triumph but in a sober account of how unchecked power consumes
everyone in its path.
