Twin brother and sister Dipper and Mabel Pines are in for an unexpected adventure when they spend the summer helping their great uncle Stan run a tourist trap in the mysterious town of Gravity Falls, Oregon.

The characters we met a little more than a decade ago return to East Great Falls for their high-school reunion. In one long-overdue weekend, they will discover what has changed, who hasn’t, and that time and distance can’t break the bonds of friendship.
