Golden Slumber - Yoshihiro Nakamura

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. Among the many puzzles of this twisty, clever film is how Nakamura manages to sneak a genuinely moving tribute to friendship into the madcap procession of perilous events. No matter what befalls Aoyagi, his friends and parents believe in him because of his steadfast, almost irrational pleasantness.
