Based on the manga created by Kenichi Sonoda (who did the mechanical designs for the original Bubblegum Crisis and later created Gunsmith Cats in response to Riding Bean being canceled), this one shot OAV chronicles the antics, shenanigans and misadventures of the title character, [Riding] Bean Bandit.
Bean Bandit, AKA: the Road Buster, is a superhuman outlaw courier who transports pretty much anyone/everyone and anything/everything for the right price (except drugs). His partner in crime is Rally Vincent, a woman with a big gun and a sharp eye on their bank account. Naturally, they're not really villains, they're just good hearted people on the wrong side of the law. When Bean is asked to transport the daughter of a millionaire, he and Rally get framed for kidnapping by a child molester named Semmerling and her little girl slave Carrie. This begins a high speed conspiracy chase with Bean determined to settle the score and reunite the girl with her father. Relentlessly pursuing Bean is Percy, a deranged police officer who's obsessed with either capturing Bean any which way he can or killing him.
Good mindless testosterone fun. Bean's such a lovable goof-ball that it really breaks your heart that his antics were discontinued. A redesigned Rally later became the heroine of "Gunsmith Cats" and a slightly different looking Bean made a few appearances in her alternate universe books.

"Eat, drink, smoke, watch TV and gamble. It's a tradition." - Bean Bandit
