With his unique ‘opening’ ability,
he can unlock anything — even people — to get the information
he needs to hunt down criminals and solve crimes.
Enter Locker — his polar opposite and his enemy.
When Locker uses her ability to ‘lock’ a witness
and prevents Kim from accessing key information in a crucial case,
they plunge into a cat-and-mouse game with justice itself at stake.
When two equal forces collide, who will emerge the victor?
