This film tells about the twists and turns of the lives of four lovers who must each overcome different fears and problems as they face the beginning of a new year. The four pairs consist of Ji Ho and Hyo Young, Jae Heon and Jin Ah, Yong Chan and Yao Lin, and Rae Hwan and Oh Wol.

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.

Some may dream of, some may be afraid of, some may look forward to, and some may want to avoid THE NIGHT BEFORE MARRIAGE! 4 different couples disclose 4 different stories all about marriage.
