Golden Slumber (2010)

When easy-going Aoyagi meets an old friend for a fishing trip, he ends up drugged, framed for the Prime Minister's assassination, and on the run from corrupt cops. It's only the beginning of what quickly becomes the worst, weirdest day of his life. But he'll get by with a little help from his friends, who include a famous pop diva, a rockabilly deliveryman, a crippled old gangster, and the world's most cheerful serial killer.
