Secrets of Sulphur Springs

It's time to get rid of the ghost.

Returning to the past, Griffin and Harper watch a murder unfold. The twins and Topher go to an unknowingly familiar someone for help.

In 1947, Harper and Griffin meet Ruby. Sarah becomes increasingly freaked out by the ghost.

The kids learn the ghost has been listening to them and is changing up his malevolent plans.

The twins arrive in the past and find Savannah. Griffin and Harper realize they need to go back to 1947 just as Ben makes the bunker off-limits.

Griffin, stuck in the future, learns the ghost ruins their lives. Harper and Savannah try bringing him back to the present.

Harper and Savannah retrieve Griffin from the future. Sam and Griffin face the grimmest truth, Topher is in a coma in 2024. The twins and Topher almost catch Savannah's "ghost."

In the midst of the grand reopening of The Tremont, Griffin and Harper receive an ominous message from Mrs. Barker.

Harper makes a big promise to Daisy; Harper and Griffin share an original document about the Tremont; Grace makes an unexpected appearance.

Harper realizes the true reason Grace's ghost sent her into the past, and The Tremont experiences an unexplainable power surge.

Griffin enlists Daisy to see what Topher is hiding, and Harper's encounter with a judge sets in motion a deception that changes the course of The Tremont forever.

Young Sam secretly watches Harper search for the hatch in the dead of the night, and Elijah receives a visit from a judge with a life-altering offer.

Griffin frantically searches for the missing crystal and helps a panicking Daisy to navigate her modern surroundings; meanwhile, Harper has a cryptic vision at the springs.

Griffin, Savannah and Harper find themselves face to face with Harper's carbon copy, Daisy, and the Tremont ghost sends Harper and Griffin an important message.

Harper pretends to be Daisy to learn her family's secrets, and Topher stumbles upon the hidden bunker.

Harper travels back in time to the date her father died in hopes of trying to change the outcome.

Griffin and Harper successfully travel to the past, where they find Savannah working at The Tremont.

Once Griffin and Harper learn they can’t reopen the hatch to let Savannah in, they quickly go back through the portal.

Harper and Griffin escape after being detained by the police and find young Jess, who reveals new details about her relationship with Savannah.

Griffin and Harper are grounded after they are caught together outside of The Tremont. Soon after, they sneak back through the portal with the hope of still finding Savannah.

Griffin and Harper observe as young Ben and Savannah sit around the post-dance campfire when, suddenly, Savannah is spooked by a counselor dressed as the legendary Moss Man.

Ben is upset by the flurry of news reports marking the thirtieth anniversary of Savannah's disappearance, while Zoey and Wyatt see it as the perfect opportunity to finally capture her ghost on tape.

Harper asks Griffin to meet her at the portal after school, but, when Griffin gets home, he discovers his Grandfather has arrived for a visit.

Griffin Campbell and his family have just uprooted their lives to move to a new town and take ownership of an abandoned hotel in hopes of restoring it to the lively vacation destination it once was. Not long after Griffin begins his first day at a new school, he learns that the hotel he just moved into is rumored to be haunted by the ghost of a girl who disappeared decades ago.
