A girl buys an evil-looking artifact at a garage sale that a woman smilingly tells her, "It's a friendship game. You put your hands on it and speak your innermost desire. If your friendship doesn't survive the game, neither do you." So of course she buys it and plays it with her friends. Unfortunately the woman didn't tell her the other part of the curse: it puts you in a movie with a totally nonlinear narrative that makes no sense.
