Season 1

Rejected by law firms, Shin I-rang rents an eerie old office and lands his first job: a medical malpractice case for a ghost and his grieving wife.

After ghostly client Lee Gang-pung possesses him, I-rang reconsiders their arrangement — until a crisis renews his conviction.

The ghost of a teenage girl haunts I-rang in his office, demanding he acknowledge her existence and find out who she was.

I-rang vows to reveal the true perpetrator behind Su-a's case. With this in mind, he enters a temporary alliance with his lawyer nemesis, Na-hyun.

I-rang's new case involves a gifted scientist who died at the hands of his wife. The wife's defense lawyer turns out to be none other than Na-hyun.

Mistakenly linked to a murder, I-rang must race against time to solve the case and prove his innocence.

When I-rang loses his ability to see ghosts and Na-hyun suffers a career setback, the two cross paths again at the courthouse.

A possessed I-rang acts out at a crime scene and gets arrested. While locked up, he discovers the identity of the ghost who caused his outburst.

Na-hyun spends precious time with her sister thanks to I-rang. But her emotional wounds deepen behind the facade of a happy family reunion.

I-rang and Na-hyun officially launch their partnership. On their first day, a vegetable vendor arrives at their office seeking legal help.

After dropping a compromised case, I-rang and Na-hyun hunt for a new lead upon hearing rumors that Seon-hwa is still alive. Their investigation uncovers a suspicious accident from her past that could change everything.

While helping a young ghost uncover his identity, I-rang finds a mysterious link to an abandoned golf course. Meanwhile, Na-hyun’s feelings for him deepen as they search for the truth together.
