Two young lawyers in Jiang City reunited in a live broadcast of a domestic violence and anti-homicide trial. They stood on opposite sides, speaking sharply, but no one knew that each other was the most important presence in the other's childhood. Gu Zhun is rational and cold, and has the highest winning rate; Su Wanyi is gentle and firm, and believes that the law should have warmth. When a "strategic marriage agreement" binds them under the same roof again, they pretend to be in love in front of everyone during the day, and sleep in different rooms under the lamp at night. The boundaries between truth and falsehood, calculation and heartbeat gradually get out of control. However, an old case that had been dusty for twenty years reappeared between the two, and the past events of their father's generation were intertwined with the real case. Some people are pushing for the truth in the dark, while others are trying to bury the fire. When love and justice stand on the same court, they must answer a question - if the truth will burn everything, are you still willing to testify for each other?
Under the blazing day, no one can remain silent forever.
