Then:
During the Nazi Occupation of Poland, Dr. Josef Mengele conducted sadistic experiments on twin children. Nathan Oberst barely survived the torture of the death camp, but had to watch his twin, Noah, die before his eyes. At that moment, Nathan witnessed the ancient evil behind Mengele that fed off the misery and deaths of the children. As the sole remaining survivor, it is up to Nathan to stop it.

Now:
Jason Collins and his twin, Jimmy, go on a vacation with their parents to Sau Paulo, Brazil. Their rent house is haunted, scaring all the occupants out within a matter of days. In a panicked frenzy their dad wrecks the car, killing everyone … except for Jason. He is now orphaned and blinded.

After returning to the United States, Jason adjusts to living with his Uncle Dan, Aunt Janie, and his cousin. Much harder, though, is adjusting to his blindness. As his hearing intensifies, he can now hear the voice of something supernatural that haunts the family.

Meanwhile, an aging Nathan has linked Mengele to an abandoned rent house in Sau Paulo where Jason and Jimmy stayed. He finds their belongings and sees they are twins. Worried, he must find them – knowing Angel of Death is after them. Nathan might have the secret to rid the earth of the demonic entity, but can he find the family in time?
