Secrets of Sulphur Springs (Seasons 1–3)

Secrets of Sulphur Springs (2021) is a Disney Channel family series you can watch online on iFILM. Twelve-year-old Griffin Campbell moves with his family to a small town, where they take over a long-shuttered hotel with a dark reputation — a girl vanished there decades ago, and locals still talk about her ghost.

Classmate Harper pulls Griffin into the mystery, and the two stumble onto a hidden portal inside the hotel that sends them straight into the past. The disappearance turns out to be far more tangled than any ghost story: the old timeline connects to Griffin's own family in ways neither kid expected. The series spans multiple seasons, each one pulling the time loops tighter.

For a Disney family show, the plotting here is surprisingly tight — the time-travel rules hold together and the mystery actually pays off instead of spinning in circles. Stream Secrets of Sulphur Springs (2021) online on iFILM.
