The Tag-Along: Devil Fish

An old Taiwanese legend introduces a fish with a human face. Three men catch the strange fish in central Taiwan and hear a chilling question from it: Is the fish meat tasty? The moment marks the beginning of a haunting that threads through the film.

Following the catch, malicious spirits descend upon the community and begin to torment nearby people. A temple priest, a young boy, and the boy's mother become targets as they struggle to understand the apparition and protect their home. The encounters set the tone for the gathering danger throughout the story.

The demon's origin is tied to a disfigured son of a wealthy man, Mr Chung. The father abuses the boy because of his rare skin condition, and the boy dies as a consequence. His vengeful spirit is then seized by a malevolent demon, unleashing a dangerous force.

The demon, amplified by the possession, begins to haunt Mei-Hua's daughter. This arc traces how the girl grows increasingly troubled until she transforms into the girl in red that anchors the original film's lore. The possession marks a turning point linking the backstory to the events beyond.

Lin Chun-Kai's father, a master shaman, confronts the demon with aid from the Tiger Lord's spirit. He fights bravely but pays with his life, ensuring the demon's threat remains unresolved for the time being. The sacrifice underscores the gravity of the haunting faced by the families involved.

After his father's death, Lin Chun-Kai is taken in by his grandfather, a seasoned master shaman who trains him. The old mentor teaches him to carry on the family legacy and protect people from restless spirits. This lineage becomes the foundation for the upcoming Tag-Along storylines.

The grandfather imparts shamanic knowledge and ritual skills, preparing Lin Chun-Kai to become his father's successor. The training deepens his resolve to confront the demon's ongoing menace. He learns to balance healing, ritual power, and protection.

The demon's power ripples through the community, affecting more people beyond Mei-Hua's daughter. Lin Chun-Kai and his allies piece together the source of the unrest and brace for a long fight ahead. The haunting tests their faith and ritual craft.

The Tiger Temple's younger generation, including the temple's priest's son and his grandfather, appear within the backstory, hinting at their future roles in The Tag Along 2. Their presence ties the prequel to the ongoing series. The shared mythos strengthens the links between films.

The possession that becomes the Girl in Red is linked to the demon's awakening during Mei-Hua's daughter's life. The haunting leaves a lasting mark on the family that resonates with the original film's tone. It clarifies how a familiar image from the later film originates.

Lin Chun-Kai is groomed to be the successor of the grandfather's shamanic line. He learns to combine ritual power, healing, and protection to guard against the demon. His development in this prequel sets the stage for his leadership in Tag-Along 2.

The film closes by confirming Lin Chun-Kai's destiny to inherit the mantle and confront the demon's legacies. The origin story explains the shared mythos that threads into The Tag Along 2. The film ends with anticipation for what comes next in the series.
