Tucked away in a remote forest, the convent of Adoration is inhabited by a group of nuns seeking a peaceful life of devotion and discipline, filling their days with nothing but mundane chores and prayers. But the wish for a life in isolation is threatened when President Ferdinand Marcos declares martial law, and political protests and chaos begin to infiltrate every corner of the archipelago. Suddenly, the nuns find themselves engulfed in violence and unrest that will eventually put their faith and conscience to the test.
