The Perfect Lie

Joonho, a heart surgeon with a perfect smile, and Jisun, a free-spirited teacher-librarian, are drawn together after a chance encounter and share a special night in the pouring rain. But the next morning, something seems to be up with Jisun.

After that night, Joonho and Jisun face each other at the police station with completely different memories; with no evidence or witnesses, both take a polygraph to prove their innocence, but the result points to an unexpected name.
