Jung-min, a rookie lawyer, becomes Yoona’s public attorney, as she is accused of murdering her husband. Against a nasty prosecutor, a mysterious judge, and all the suspicions surrounding the defendant, Jung-min seeks to unravel the truth behind the conspiracies of the case.

One of the many reasons why court-thriller films are not often produced in Korea is that Korean court trials are not as exciting as those in the West. Havana tries to prove that a thrilling, twisted court drama can be made in Korea, while set in a dry and monotonous Korean courtroom. The defendant in this court is Yoona, a woman who pleaded guilty to murdering her husband. Jung-min, a new lawyer, is appointed as a public defender for Yoona's case, but he is convinced of her innocence and eagerly prepares for the trial. The film uncovers the truth of the case, centering on repeated trials. It unfolds quickly when an unknown person delivers a message to the lawyer and another mysterious person that Yoona met on the day of the incident appears. This film harmonizes with the uniquely chilled atmosphere of the thriller genre and the passionate love of the secret person behind the main story. [MOON Seok]
