The Tag-Along: Devil Fish (2018) Timeline Explained – Every Event in Order

The demon originates from the vengeful spirit of a disfigured son of a wealthy man named Mr. Chung. The boy had a rare skin condition that made his father ashamed, leading to severe abuse. After the boy died from his injuries, his angry spirit was seized by a malevolent demon, creating the dangerous force that haunts the community.

Foreshadowing: The film's backstory hints at generational trauma, showing how cruelty toward a child eventually manifests as supernatural evil.

The human-faced fish legend serves as the thematic entry point connecting Taiwanese folklore to the main narrative. While the fish itself is a separate supernatural element, it represents the film's folkloric foundation. The legend establishes that disturbing supernatural entities can emerge from seemingly ordinary events, setting the tone for the demon's awakening.

Foreshadowing: The eerie question '魚肉好吃嗎?' (Is the fish meat tasty?) echoes through the film as a warning.

The demon feeds on fear and weakens spiritual boundaries, allowing its influence to ripple through families and temples.

Tiger Temple serves as the spiritual battlefield where the demon is first confronted. It is the home of the master shaman lineage, including Lin Chun-Kai's father and later his grandfather.
