A boy is found burned to death at his grandfather's extremely poorly coded house. The investigation reveals the grueling disasters preceding the fire, and the murder of the handyman on site.

Tropes

• Offing the Offspring: The grandfather accidentally killed his grandson while setting fire to his own house.
