what happens

The Suicide Ray Gun - once you're hit with it, it causes a sickness in which one wants to die as soon as possible. When the inventor of this weapon turns to evil, stopping it is no easy matter. Bandit leader Basara is the man with the gun, and he tries to wring out of Lupin the location of a diamond he's hidden in India. He even tries a fake Fujiko when all else fails to get Lupin to talk, but... What is the specific remedy for death-wish sickness?!
