The Stevens think that they've won an all-expenses-paid trip to an island that's halfway around the world. When their house is destroyed, their food stolen, and their bacon eaten, the Stevens family breaks apart in front of all their friends on live national television, while the island itself is only a short distance away from Sacramento!
Decent watch at best, probably won't watch again, and can't recommend except for hardcore "Even Stevens" fans.
I specifically binged "Evens Stevens" for this, and the show, even dated, is much better than the movie. This is clearly designed to be an extended episode of the show, but dramatically fails in the pacing that the show was so good at.
While I'm a big fan of Christy Carlson Romano, Shia LaBeouf is only a little less crazy than his adult self, and it is the introduction of Tim Meadows that is the big difference in the plot.
A mix of "Stuck on an island", "Secret Reality Show", and "Disfunctional Family" tropes, it really is just a lot of "let's mess with this family" for most of the movie. They stray away from the traditional use of family values to exploit the infighting to a point where they act like they're thinking about eating one another.
It's fun, but I can't imagine anyone who doesn't have history with this family are going to enjoy the movie.
