All three new hunters ended up in the tiny town of Rodbum, Ohio (nothing to see here, folks, move along) for their own disparate reasons. 

AJ had stopped on his way towards Maine, following a very weak lead on his Great Uncle's journeys. 

For Lindsey, it was just across the border from Pennsylvania, where she had last been and her parent's people were all over that state — she totally wasn't hiding out in a nice suite in an expensive hotel pampering herself before heading to visit the house from A Christmas Story… 

And Walter was searching for other hunters, to learn from and to do some networking.  But he had a bad tip that there'd be a couple near Rodbum, or a tip that a bad couple would be at Rodbum.

Each following their own instincts and leads, the hunters all wound up at an abandoned house where some missing kids had been last seen.   Searching together, they came upon a spirit on fire.  Using their combined wits and knowledge, they managed to defeat the ghost.

On the following day the group, after having rested and caught each other up on what they knew, returned to the abandoned house.  They searched for, and found the remains of, the missing kids.

Men searching for Lindsey had tracked her down, thanks to her infamy and a hotel clerk with a smartphone.  Again, in their own unique style, the crew evaded the hired thugs, dealt with a motorcycle crashing into a cop car, and even managed to vandalize and burgle a roadside attraction.
