Go Mi Ran is a young jobseeker who is told she will be given around US$ 4,200 if she takes part in a cryogenic freezing program. She is told that she will be frozen for just 24 hours and then leave with her money.

Also being frozen is Ma Dong Chan, a popular entertainment TV producer who is cold as ice when it comes to working – but tends to get hot and passionate when it comes to affairs of the heart.

But instead of waking up a day later, the duo awakes from cryogenic slumber to find they have slept through 20 years. All the people Mi Ran and Dong Chan once knew have aged by 20 years, but their own bodies and memories have not changed at all.

Life 20 years in the future is not easy – and things are made harder for the duo when they discover that should their body temperatures rise above 33 degrees Celsius, they will die.

When Mi Ran and Dong Chan begin developing feelings for each other, temperatures start to rise…spawning all sorts of dramatic consequences.

Will the duo fight back the heat of a potentially fatal romance? And will they discover the mysterious reason why they were frozen for two decades – and the role of the enigmatic Dr. Hwang, the shady figure behind the freezing project?
