After returning home from a cattle drive in the rolling fields of Colorado, twins Spencer and Maggie Parker think they must have been dreaming. The camper that showed up in their driveway on the last day of second grade couldn't possibly be magic. There's no way a camper can transport them to every state in the continental US... or is there?Needing to know if it was all in their head, the twins sneak out to test the camper's abilities, and end up in the middle of Times Square in New York City! There they run into super-star Hallie Hampton, who needs their help on a scavenger hunt around the city. If the twins can help Hallie complete the hunt before curtain call, she'll give them two tickets to her debut on Broadway. But the hunt might not be the only thing the twins need to do to help Hallie and find their way home again.
