Dear Tenant

Yo-yu is a 9-year-old orphan who lives with his grandma and Mr. Lin, the tenant in their rooftop flat. Lin looks after Yo-yu and tends to the daily needs of Grandma, who suffers from late-stage diabetes. In everyone's eyes, Lin is a kindhearted gentleman. But when Grandma passes away, everything changes. Yo-yu's uncle Li-gang returns to Taiwan and discovers that ownership of Grandma's apartment was transferred to Yo-yu, whom Lin has legally adopted: the property is now effectively under Lin's control. Li-gang contacts the police with his suspicions. An autopsy finds narcotics in Grandma's system, prompting an investigation that reveals a very different side to Lin. Police recover a deleted gay-sex app on Lin's cell phone, and one of his hookups turns out to be a drug dealer. Just as he is about to be arrested for Grandma's murder, Lin takes Yo-yu and flees deep into the mountains.
