Dear Tenant

Yo-yu is a nine-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 only to discover that ownership of Grandma’s apartment was transferred to Yo-yu, who has been legally adopted by LIN. In other words, 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 at the time of her death, 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…
