Doubt is an exciting and unconventional new legal drama about a prestigious boutique New York firm headed by a legal legend. The practice attracts top talent looking to prove themselves, including a brilliant lawyer who finds herself falling in love with a client—a prominent pediatric surgeon accused of a brutal murder committed in his youth.
Brilliant and beautiful, Sadie Ellis has a good job at a boutique law firm where she works with passionate warrior for justice Cameron Wirth, second-year associate Tiffany Simon, former felon Nick, and her close friend Albert Cobb, who believes he knows everything about her -- but Sadie has a secret that could put everything on the line. Clandestinely involved with her charming client, Billy Brennan, a pediatric surgeon accused of murdering his girlfriend 24 years ago, she must work harder than ever to prove his innocence, even if she's not always certain of it.
As Sadie tries to keep her relationship with Billy strictly professional, she works on a case involving one of Isaiah’s oldest friends, Jonah Porter (Sam Anderson). Also, Cameron is conflicted about whether or not to convince her client to testify against his own cousin in order to avoid jail time for a murder he didn’t commit.
Sadie confronts Billy about new evidence in the case against him and is disappointed when his explanation is not what she expected. Also, a piece of evidence in a new case for the firm could unexpectedly expose a massive scandal, and Cameron and Tiffany defend a psychic accused of grand larceny.
Sadie interviews Billy's ex-classmates hoping to find information about a key piece of evidence. Also, she defends Elena Garcia, her childhood best friend, in a probation violation case; Cameron is asked on a date by her former classmate, Peter; Albert's unpredictable father Tyson comes to visit; and Isaiah faces off in court against Ivan Sturgill, his former law partner and current rival.
When the DNA results come back in Billy's case, Sadie avoids the gag order placed on revealing them by making a scene in court to bolster public support for him. Also, Albert is tormented by his client, Rodney Hill, who divulges information about the location of his murder victim, knowing that he is protected by attorney client privilege, and Cameron represents Tessa Pratt, who was issued a cease and desist order for publicly shaming her rapist.
In the midst of Billy's trial prep, Isaiah and Sadie visit her mother, Carolyn, in prison after they learn important information regarding her former accomplice. Also, Cameron and Albert defend a transwoman arrested for stabbing a famous baseball player, and Cameron finally gives into her feelings for Peter.
Nick and Tiffany help Sadie and Albert review audiotapes from Billy's sister's old therapy sessions, hoping to find clues in the murder case against him. Also, Sadie serves as counsel on the divorce proceedings for Isaiah's daughter, Dylan, and Cameron agrees to represent Carolyn in her upcoming parole hearing.
Sadie must testify at Carolyn's parole hearing on her qualifications as a mother, but a man from Carolyn's past resurfaces, hoping to scuttle what may be her last chance at freedom. Also, Nick takes on his first case since passing the bar and is up against the DA who put him in prison, and Cam takes her relationship with Peter to the next level.
When Albert discovers the truth about Sadie and Billy's relationship, he steps in as first chair on the murder trial, fearing Sadie's judgement is compromised. Also, Cam and Nick defend a client accused of conspiracy to commit kidnapping, Isaiah takes a break from the firm after the outcome of Carolyn's parole hearing.
With opening statements looming in Billy's trial, Albert and Sadie struggle to rebuild broken trust and do their best for Billy as the prosecution lays out a devastating case. Also, Peter and Cam face the first crisis of their budding relationship when Peter considers a run for District Attorney.
Billy upends his case when he chooses to go against the advice of Sadie and Albert and decides to testify in his trial. Also, Cam must decide if she will forgive Peter, and Nick and Tiffany defend a former prison friend of Nick's.
Sadie gives her closing argument in Billy's trial and the jury begins deliberating. Also, Sadie learns about Carolyn's cancer diagnosis, and Tiffany and Cameron defend a woman who murdered her best friend while allegedly sleepwalking.
After the jury delivers their verdict in Billy's trial, Sadie learns he has a secret that might have impacted his case. Also, Billy uses a favor owed to his family by the governor and gets Carolyn released from prison, and Nick is charged with the murder and Isaiah and the firm rally around him to get him released.
