A true historical drama about King Sejong, the greatest ruler in Joseon history who sought to enhance national prosperity and military power through astronomy, and Jang Yeong-sil, the most remarkable scientist.

A teenager is abducted and forced to tell the scariest tales she knows, leading to this anthology of four stories: a brother and sister are under siege while home alone; a killer escapes police custody mid-flight; step-sisters take plastic surgery to nightmarishly macabre extremes; a paramedic and mother standoff over her infected young daughter.
