Galaxy Express 999 - Season 1 Episode 70 Heart of Flower Village

The 999 stopped at the City of Flowers, which was covered with flowers. When Tetsuro and Maetel went to the Hotel, a fire broke out that ravaged the planet (and the flowers). The train made an emergency take off, while Maetel and Tetsuro were rescued by Coa and Rea (who started the fire), and their children Mia and Doa. The flowers, Coa explained, were poisonous, and those who destroyed them were executed. The police discovered Coa's role, and ordered his execution. The family refused to come out, and the ploice threatened to seal their entrance. The people rose up in defiance, however, and the police captain was forced to back down. Now on board of the 999, Maetel and Tetsuro contemplated on the significance and irrationality of Coa's (and his family's) sacrifice.
