The characters in this movie are spunky and self-determined, although they also make some bad choices that get them in water that is way over their head. They get caught in the middle of the theft of a prize-winning racehorse and have to use their wits to escape, and, ultimately, to help the people they would rely on to save them, as well.
My seven year-old is a sensitive viewer, so what the reviewer, above, calls tame is about as tense as she can take. There were scenes of struggles, the kids were chased and some people wind up with their hands tied. But the action was mostly slapstick and the children were frequently leading the thieves on to trick them.
As an adult, I enjoyed the inventiveness of the kids and got caught up in the plot as well. It's on our list of family-friendly movies!
