Plot
The movie is based on another famous Taiwanese urban legend, a ghost story that involved three men catching and grilling a fish in central Taiwan only to notice a face appear as they began to eat it. They then heard a voice ask them, in Taiwanese, 「魚肉好吃嗎？」 ("Is the fish meat tasty?").

The story of 人面魚 (fish with a person's face) is a well known folktale in Taiwan. Tales of a fish-like creature with a human face, similar in a way to Japanese yokai, has existed in Taiwan for decades. The film introduces the same folktale of the three men catching the fish and hearing the famous sentence at the start, then the plot then follows the efforts of a group of people, involving a temple priest, a young boy and the boy's mother as they are harassed by malicious spirits brought on by the caught fish.

After completing the Tag Along story, the creators of the film wanted to make a movie about another Taiwanese folk tale, choosing the Devil Fish, potentially starting a series in which they could cover more Taiwanese urban legends in the future. The film is also set before the events of 紅衣小女孩2 (The Tag Along 2), including the young son of the Tiger Temple priest and his grandfather who both appear in The Tag Along 2 working at the Tiger Temple, with the son being the boyfriend of a missing girl in the story.

The plot of prequel explores Lin Chun-Kai past and the origin of the demon that possessed Mei-Hua's daughter that made her the girl in red in the first place. It is turned out that the demon is born from the vengeful spirit of a disfigured son of a wealthy man, Mr Chung. Mr Chong's son was born with a rare skin disease that gives him the skin that looked like the scale of a fish. Mr Chung heavily abuses his son due to his disfigurement and accumulating in him, killing his son. His son's vengeful spirit is then harnessed by a malevolent demon to wreck havoc on the people. Lin Chun-Kai's father, a master shaman successfully fights off the demon with the help of the Tiger Lord's spirit but at the cost of his life. In the end, Lin Chun-Kai is adopted by grandfather who is also the master shaman and trains him to be his father's successor, leading to the event of Tag-Along 2.
