I could see the producers showing this to investors and saying "this is the future of movies". It's kind of overdone, like showing the most extreme examples of the 3D effect really getting in people's faces. That, seemingly, is the only reason for it's existence. It was part of a short revival of the 3D process, and i remember seeing it in a theater and thinking at the time how cool it was.
What's the plot? Well, a guy in a red windbreaker walks around and does some "treasure hnting" stuff, while things pop up at him (and us) in a vaguely surprising way. There really isn't any other plot than that. It could be argued that it was based on the popularity of "raiders of the lost ark", but you could actually argue just as convincingly that it's based on "the ghost and mr. Chicken". Recommended just for the flat out gimmicky-ness of it.
