I'm watching this pretty awesome show called Eden of the East.
The main character wakes up naked in front of the Whitehouse with nothing to his name but a gun and a cellphone. He eventually learns he wiped his own memory for reasons unknown, and that his phone connects him to a woman who can grant absolutely any request immediately, from assassination to manipulation of government installations. It's also got about 8 billion yen in digital money on it, which he's required to spend on saving Japan, or die. He's one of 12, all competing to be the one who survives.
It's pretty awesome.
