Ash is forced into a meeting with his adopted father, crime boss "Papa" Dino Golzine, but with Colonel Foxx still on the prowl, and a damaging news story about to break, the situation quickly turns into a final showdown.
Ash has escaped from the mental institution where he was being held captive, taking with him proof of the dangers of the mind control drug banana fish, but crime lord "Papa" Dino Golzine is not about to let Ash go, and hires the mysterious Blanca to recapture the young man at any cost.
The news that Ash has died devastates Eiji, but Ash's posse suspects the truth--that something more sinister is afoot--and begins to make plans to free Ash from the special medical facility where crime lord "Papa" Dino Golzine has arranged for him to become a guinea pig for testing of the mind control drug banana fish.
Ash Lynx, the adopted heir of a crime boss, rejects his father's kingdom and sets up his own gang; however, a chance meeting with a dying man leads him into conflict with his father's mafia and provides a clue to his brother's post-Vietnam madness.
