A shy guy who wanted to be an archaeologist gets convinced by his friend to go into some catacombs in search of the secret tomb of a princess. The group is formed by seven people, all of them young people that shouldn't be getting into strange places. Of course, things take a turn for the worse soon.The idea of "Tomb Mystery" (a group of friends find a map and decide to take a look with surprising consequences) is not a bad one, but the execution is laughable. The movie may have an interest for people into this kind of movies that are bad at all levels (acting is horrible, direction is conspicuous by its absence, no, really, the effects are something from another era, and the plot... oh, the plot... this is a movie that maybe has a plot, lost somewhere, but don't expect anyone to be able to find it; it is harder to find than the tomb of the princess). If that all wasn't enough to make the movie a painful experience (even if it is just 1 hour 25 minutes) you get gratuitous moments, like characters having to burn their clothes so they get into their underwear."Tomb Mystery" shows that an idea doesn't make a movie. If you can call a bunch of people getting into some random catacombs an idea.
