Written by Shinichiro Watanabe, the creative force behind Cowboy Bebop and Samurai Champloo, A Detective Story is the second segment of the Animatrix series of animated shorts. Styled like a film noir, the story follows a hard-edged detective named Ash, who's hired to track down the identity of a hacker that goes by the alias Trinity. He soon learns that other detectives have failed at this task, winding up dead, missing, or insane, but he eventually achieves a level of contact with the mysterious person - and finds out who he was working for. We learn that agents had bugged him to find the elusive target he was chasing, and when he comes face to face with her, he can see why.
