For twenty years, zoo janitor Zane Morales watches animals pace themselves into the dirt, carving grooves of confinement that mirror his own quiet unraveling. As repetition and neglect harden into obsession, Zane begins to believe the animals understand something humans refuse to see. On a crowded summer afternoon, he makes a deliberate choice that turns routine into reckoning. When cages open and order collapses, the zoo becomes a mirror of human cruelty and animal instinct, and Zane finally steps out of the circle—leaving behind silence, blood, and a groove that slowly fills in.
