In a postapocalyptic world, Slash hones the psychic ability he shares with the remaining members of his street gang, the 'Brothers', while in hiding. After an enemy attack, they traverse the ruined city and encounter Hilo of the rival gang 'Soooooots', who harbors resentment after the enemy, whom Croak dubs the 400 Boys, wiped out his crew. Slash proposes a parlay to unite the surviving gangs against the 400 Boys. Their path is interrupted by Bala of the 'Galrogs', who leads them to consult with the Old Mother. She reveals that a past war broke the world, allowing "outside beings" to "ooze through the cracks." The newly allied gangs gather more fighters and confront the 400 Boys, who manifest as violent, destructive gigantic babies. Despite suffering heavy losses, they manage to defeat the 400 Boys one by one, with Slash executing the last of them.
