Bull works to convince a jury that an alleged murder was actually a tragic accident when TAC represents a woman charged with her 3-year-old stepdaughter’s death.

As Bull prepares for fatherhood, his work at TAC suffers without his top attorney, Benny, who quit in reaction to Bull’s romantic reconnection to his ex-wife and Benny’s sister, Isabella. In addition, the team faces a difficult time in court as they mount a defense for a young bartender on trial for involuntary manslaughter.
