The film stars Nonie Buencamino and Sid Lucero as Jesuit priests and forensic investigators Gus Saenz and Jerome Lucero, Carla Humphries as journalist Joanna Bonifacio, with Gladys Reyes, Ricky Davao, Bembol Roco, TJ Trinidad, Christopher De Leon and Tessie Tomas in supporting roles.

This is also the last film appearance of Joy Viado, who died of a heart attack in Diliman, Quezon City on September 10, 2016, at the age of 57.

Both Gus and Jerome raised doubts on the veracity of the arrest as the evidence was inconclusive, so they asked people such as Rommel, who knew Carding to gain additional clues.

The two priests were invited to an opera at the CCP and there they encountered Cardinal Meneses and Mrs. Urrutia, the head of a children's charity.

The pair gained a lead when they were able to identify a potential suspect, Dr. Alejandro "Alex" Carlos, a dentist who came from Payatas and graduate of UP Manila.

Alex barged into the health clinic and stole some medical tools from Dr. Gino, the person the pair interviewed earlier.

Gus was able to recover from his injuries and Alex was found dead at Payatas, with multiple self-inflicted stab wounds.
