A Normal Family (2023)

Successful attorney Jae Wan takes on the case of a wealthy executive's son who intentionally ran over and murdered a man and gravely injured his daughter. To defend a killer is part of Jae Wan's profession, another rung on the ladder of his career. On the other hand, his younger brother is a devout and honorable pediatrician who consistently prioritizes the health of his patients before personal gain and profit, frequently breaking the regulations of the private clinic where he works. When an unexpected circumstance involving their teenage children emerges, the brothers' consciences are tested, and their regularly scheduled dinner talk takes an unexpected turn.
