In 2014, Zak Bagans, host of Discovery Channels, Ghost Adventures, purchased a small one-story home in Gary, Indiana. So that he could make a documentary. The lore came from when the house made national attention as being dubbed the "Portal to Hell" when its tenants, years prior, claimed demons were taking up residence alongside them.

Some believe the story was fabricated while others, including a 37-year veteran of the Gary Police Department, believed it. The events that unfolded led to one of the most unusual cases that Department of Children's Services had ever handled, but this story ends with Zak's documentary.

It begins with a single mother and her three children. This is the possession of the Ammons family.

Christmas in 1700 England was a true site to behold. Bows of holly and ivy wrapped around street lamps and entryways, aroma of mid-winter feast, including jolly cakes. Roasted duck and rich gravies filled the air while the distance sound of carers could be heard at every turn. Performers in lavish costumes would take to the streets to celebrate the birth of their Lord and Savior.

But when one such performer was violently struck by a supernatural force causing bizarre and frightening behaviors, many were divided on if this was a case of a melodramatic actor or did something evil enter him that day, causing an 18 year battle with the devil. This is the possession of George Lukins.

On October 3rd, 1869, a young boy was exercised at a chapel in the orphanage where he resided. However, he wasn't your typical orphan as he had a family who loved him, but could no longer care for him after they claimed he became possessed by the devil.  His behaviors, including twisting his limbs in various directions and violent outbursts, was the catalyst for the family to relinquish him while he awaited exorcism.

But one of the most striking things about this case is that it wasn't just one child from this family who was under spiritual attack and sent to an orphanage. It was two. This is the possession of the Burner Brothers Theobald & Joseph.

Situated in the picturesque countryside of Earling Iowa is a Franciscan convent. The warm breeze of a bright summer day in 1928 is in stark contrast to the dark soul-stirring phenomenon occurring just beyond the convent walls. Inside, a disturbed woman displays such bone-chilling behaviors that the nuns caring for her are left terrified.

This case quickly became a national sensation, and the attending Father emerges as America's most famous exorcist to date. The pseudonym Anna Ecklund was given in an attempt at anonymity, but by the time the exorcism was over, most of the country already knew who she was. This is the possession of Emma Schmidt.

In the early morning hours of October 6th, 1974, a chill was felt in the air of Ossett a small, sleepy town in Yorkshire, England, but it wasn't because it was a cool, crisp fall day. It was because an unspeakable act had just occurred. A devoted wife and loving mother to five children was violently murdered alongside the family dog in her home.

The manner in which she was killed was so evil, it left the town in a state of shock and terror. The killer was quickly identified and detained in a psychiatric hospital to await trial. Who was the killer? None other than her husband and his defense: you guessed it. This is the possession of Michael Taylor.
