After the explosive destruction of Blackwell Mansion, Danielle and Lizzy finally settle into their cabin at Dragonhead Lake. Unfortunately, not all is well. Shortly after, creepy glowing orbs randomly appear on the lake, terrifying the nearby residents. Some fear the strange occurrence to be supernatural, while others believe it is an alien invasion. At the same time, a series of random break-ins occur around the lake, spooking the locals.

Officer McGilley attempts to aid Danielle, the five friends—the Paranormal Investigators’ Club (PIC ), and their loyal dog, Amber, in solving the mysteries of Dragonhead Lake. Excited to reveal the location of the elusive fortune, the children must decipher the clues left behind by Colonel Blackwell.

While working with Danielle and the children, Officer McGilley is also forced to keep an eye on a snoopy investigative reporter, Sheryl Bimberton. She is relentless in her pursuit to cover and solve the puzzling story unraveling before her. As Sheryl researches the biggest story of her career, she discovers some rather disturbing news, which may lead to trouble for Officer McGilley and the entire Pineville Police Department.

While on spring break, the children— James, Jeremy, Stephen, Sheila, and Brandon, rush to gather clues, with the help of Officer McGilley, and Sheryl Bimberton, to solve the Secrets of Dragonhead Lake.
