Treadstone

Two years after committing mass murder at a movie theater, Li Hsiao-ming is sentenced to death. The lives of several families impacted by the shooting collide as Hsiao-ming's defense attorney, Wang She, fights for an extraordinary appeal for his client.

When Ta-chih hands in her resignation letter, Chiao-an is incensed, and Brother News searches for answers. Mei-Mei and Wang She rush to their daughter's kindergarten when a mentally unstable suspect breaks into her classroom.

Szu-yueh confronts Ta-chih about SBC's portrayal of Szu-tsung, whose mental health has taken a turn for the worse. Mei-Mei puts pressure on Wang She to reevaluate his professional and personal priorities. Meanwhile, Chiao-an and Chao-kuo are called into Tien-ching's school by a concerned teacher.

Szu-tsung receives his diagnosis. Wang She's defense of Chen Chang deepens the rift between him and Mei-Mei. In pursuit of answers and a fresh start, Ta-chih visits her parents. While Tien-ching stays with her aunt and uncle, Chao-kuo makes an effort to mend his marriage.

The members of the Ying family have an argument about Szu-tsung's living arrangements. Despite Chiao-an's out-of-control temper, Chao-kuo's support doesn’t falter. Wang She finally convinces Hsiao-ming to see his family, but their reunion is thwarted by some devastating news.

Ta-chih and Chiao-an have a public confrontation. Despite her father's disapproval, Mei-Mei sticks by Wang She's side. Following their therapist's recommendation, Chao-kuo takes Chiao-an on a painful walk down memory lane. When her father gets sick, Szu-yueh decides to take matters into her own hands.

Chen Chang is devastated when he's not given the death penalty. A middle school student spreads terror in Li Hsiao-ming's name. Meanwhile, Chiao-an has a change of heart, and Ta-chih offers her an earnest apology. Szu-yueh and Kai-tzu continue their arguments, and a discharged Szu-tsung gets a job offer from an old friend.

When the media ambushes the cafe looking for Ta-chih, she realizes she's been betrayed, and Szu-tsung is determined to protect her. Wang She makes a drastic change. To their surprise, Chiao-an and Brother News' efforts don’t affect SBC's ratings, but a new director threatens to disrupt things.

Szu-tsung disappears in the middle of an episode, sending Szu-yueh and Ta-chih into a panic. With Mei-Mei's blessing and Wang She's help, the families of Hsiao-ming's victims are finally given the opportunity to forgive.
