The ghost of a student who died at a Korean school comes back to seek vengeance and protect her friends.

Two brothers get into a sudden tragic accident and they both fall into a coma at the same time. A year later, the younger brother Dae-jin wakes up believing he is his older brother Ho-jin.

《请回答1988》为韩国tvN自2015年10月30日起播出的金土连续剧，由《请回答1997》、《请回答1994》制作班底申元浩导演和李祐汀作家再度携手合作。此剧与以往将初恋作为重心的另两部同系列作品不同，将以家族关系和邻里感情作为剧情主轴。而且1988年也是香港电影的巅峰时期，张国荣、周润发等影星在韩国皆具有高知名度，因此也可能被列为剧情素材之一。
