The team investigates the historic Mishler Theatre and the Altoona Railroaders Memorial Museum. At the theater, the owner and employees have seen the late owner walking into the wall where his old office used to be, sitting in the seats, and have heard him walking on the catwalk above the stage. At the museum, the spirit of a railroad worker has been seen. Despite some orb activity in the theater, neither site presents any good evidence of paranormal activity. During the investigation, Jason complains to Grant about missing equipment that Brian was in charge of.

The team investigates The Lighthouse Inn in New London, Conn., which is reported to be haunted by the ghost of a bride who fell down a flight of stairs on her wedding day in 1930. Drops in temperature are recorded, and Steve feels someone touch him on his back when no one else is nearby. They then travel to Ashland, Mass. to a pub called Stone's Public House, formerly The Railroad House. Here, a little girl died after being hit by a train. Glasses have been known to fly off the shelves, lights turn themselves on, and a number of other occurrences have been documented. The team records one EVP of a voice saying ""I'm not..."" and a strange light. The light may have been caused by an IR light source.

At the request of the US Coast Guard, TAPS goes to Long Island Sound to investigate the Race Rock Lighthouse. The lighthouse is now automated, but the Coast Guard officers who come to do maintenance and inspection have reported strange occurrences and are nervous about going to the site. The commanding officers hope to disprove the rumors. The team's cameras pick up strange orb activity and a fog which the investigators do not remember from the time of the video. Andy is able to follow an EMF (Electro Magnetic Field) reading that seems to move up and back down the stairs (following the course of the old caretaker when he would check on the light). More dramatic, one camera sees a chair move a few inches in an empty room. Jason tells the Coast Guard that the site does appear to be haunted.

TAPS investigates Eastern State Penitentiary, an abandoned prison with a long, colorful history and a reputation for paranormal activity. While there, they capture a strange, shadowy shape on film. After reviewing the film, Jason decides that the team should return. More orbs are caught on film, but no repeat of the shadowy figure. Efforts to duplicate the footage prove unsuccessful, but Jason and Grant see how it could have been done. Not wanting to ruin TAPS' reputation, they decide that the footage is inconclusive and put it up on the TAPS site so that the public can decide what they think.

This investigation focuses on some friends of Brian's whose home is a deconsecrated 19th century church. They claim to have seen apparitions and to have heard strange noises. Also, one of the doors in the house opens by itself. The investigation turns up only orbs caused by dust. Jason determines that the sounds and orbs are caused by the settling of the wood beams when the church bell rings. The team is able to duplicate the opening door, giving a mundane explanation. No evidence of a haunting is found.

TAPS is called to investigate an armory in New Bedford, Mass. In one room, the thermal imaging camera detects a warm mist passing in front of the lens. This is very strange, because mists are generally colder than the surrounding air. While moving along a catwalk, sound man Frank DeAngelis suddenly falls down and does not feel well enough to move for quite some time. When the video is examined, Jason sees that Frank's audio equipment actually jumps up with no visible reason and hits him in the face. The video is on the TAPS site.

Reports of disturbances in a college student group house are easily explained as acoustics and encounters with neighbors who were drunk at the time. At the Topton House Pub, witnesses have reported that the ghost of a little girl sometimes trips people on the steps and has moved glasses of soda on one table. The daughter of the owner has also smelled roses while in the cellar and heard murmurring voices. The smells and voices are explained, and no evidence is found of any other paranormal activity. Jason shows Frank DeAngelis the footage from the Armory.

Mike Sinclair, the founder of O.R.I.O.N. Paranormal and a TAPS family member, has called in TAPS to co-investigate the New Boston Inn, in the Berkshires. After examining his findings, the TAPS team is able to disprove or cast doubt upon, everything he found. However, the experience their own incident when a pen seems to have moved with no one else nearby. Next they travel to Pittsburgh to investigate the home of Gloria and Genny. Both of them relate dramatic experiences, but the team finds no evidence of a haunting.

TAPS investigates two cases. First they go to Albany, NY to the home of Linda Johnson. Linda claims to be psychically sensitive, and to have been accosted by a negative or ""demonic"" entity. No conclusive evidence is found, but Jason suggests that Keith Johnson contact her separately to try to help further. Next, they meet Adam Zubrowski, who seems to be experiencing strange events. The house was built by his grandparents, and his grandfather died there. Two odd EVPs are recorded, and it is judged likely that the house is haunted. One of the recordings sounds like Adam's grandfather.
