Sudoku

Ben Carter (Nicolas Cage) is an American cop living in Tokyo. His partner, Okubo (Ken Watanabe), dies during a drug sting operation along with several important members of the Yakuza. Now, three years later, Ben's wife and child are kidnapped and he has forty eight hours to get them back safely but whomever has them isn't making it easy.
Ben is mailed a large map of Tokyo that has been broken up into a grid holding 81 squares. Several of the numbers have already been filled in (each number representing the number of people murdered in that area) and Ben has to complete the puzzle to find the last number "2" (representing his wife and child). As Ben goes deeper into the sick, twisted world of japanese number puzzles, he discovers some interesting things about his ex-partner. Now, with the clock ticking, Ben must unravel the clues that hold the key to the whereabouts of his wife and child along with who might be behind this high stakes game of cat and mouse.
