Abyss

Go Se-yeon (Park Bo-young) is a beautiful prosecution lawyer at the top of her game, and Cha Min (Ahn Hyo-seop) is her friend, an unattractive but rich heir to a cosmetics empire. They are both revived into different bodies by supernatural beings using an "Abyss" after their deaths in separate incidents. The "Abyss" is a celestial object which has the power to revive anything that has died; the reincarnated bodies take on the appearance of that person's soul. Go Se-yeon takes on a 'plainer' appearance, whilst Cha Min becomes very attractive and young; virtually the opposite of before. They start working together to find out the reason for their revival and who caused Go Se-yeon's death.
