The first season of "The Lincoln Lawyer" left viewers on a cliffhanger, with Mickey Haller still searching for the tattooed man who had murdered Martha Renteria. In Season 2, Part 1, Mickey's life took a dramatic turn as he gained media attention and found himself in high demand among high-profile clients. It was during this time that he met Lisa Trammell, a woman accused of murdering a businessman. Despite barely knowing each other, Mickey and Lisa grew close, and Mickey decided to take on her case, even without receiving payment. However, doubts about Lisa's innocence began to emerge, leading to the question of whether Mickey would be able to find evidence to prove her innocence or if Lisa was actually the murderer.

In the previous season, Mickey had encountered a man with a tattoo on his left arm, who turned out to be the killer responsible for Martha's murder. Mickey successfully proved in court that Jesus Menendez, who had been framed for the crime, was innocent. However, knowing that the tattooed man was still at large, Mickey anticipated that the case would be reopened, and Detective Raymond Griggs was assigned to the investigation. Mickey's primary focus was to locate Glory Dayton, a key witness whose testimony could exonerate Menendez.

Before Mickey could proceed with locating Glory, he took on another case involving Russell Lawson, who was charged with breaking into his neighbor's house. Mickey successfully defended Russell and believed the chapter was closed. However, Mickey soon discovered that Russell was not as timid as he seemed. Russell, who was the tattooed man responsible for Martha's murder, strategically manipulated the situation to prevent Mickey from fighting his case and using attorney-client confidentiality in court.

This put Mickey in a difficult position. He had promised Menendez that his case would be resolved, and now he had to comply with Russell's demands. Seeking advice from David Siegal, Mickey devised a plan without disclosing it to Lorna and Cisco. Unfortunately, Mickey's plan was disrupted when Glory Dayton was caught in a drug case. Mickey confronted Glory and learned that she had received drugs from Hector Moya, a member of the Tijuana cartel. Mickey decided to use Glory as bait, striking a deal with the district attorney's office to drop charges against her in exchange for information on Hector Moya's whereabouts.

While Mickey was dealing with the tattooed man's case, Lisa Trammell's situation took a turn. Mickey had initially believed in Lisa's innocence, but evidence against her began to accumulate. A coffee mug, a shard of glass, and witness Margo Schafer placed Lisa at the crime scene. Furthermore, a missing hammer from Lisa's toolbox raised suspicions. Andrea Freemann, the prosecutor, offered Lisa a plea deal for voluntary manslaughter, a lesser charge than murder. However, Lisa maintained her innocence and opted for a trial.

Mickey uncovered information suggesting that Mitchell Bondurant, the murdered businessman, had threatened Alex Grant (real name Alex Kazarian), a contractor working on one of his projects. Mickey believed this information could help clear Lisa's name. He requested a preliminary hearing to assess the merits of the case. However, he was caught off guard when Andrea Freemann presented a forensics report as evidence. The report revealed blood stains matching Mitchell's on a pair of gardening gloves found in Lisa's garage. Mickey realized his theory had been disproven, and now it was up to him to prove Lisa's innocence.

As Season 2, Part 1 concluded, the question remained: would Lisa Trammell be convicted in Part 2? Lisa maintained her innocence, but there were doubts about whether she was hiding something from Mickey. The sudden appearance of two men attacking Mickey suggested that someone wanted to prevent him from uncovering the truth. Lorna had expressed concerns about Lisa from the beginning, but Mickey's infatuation with her clouded his judgment. The discovery of the blood-stained gloves in Lisa's possession raised doubts about her innocence.

While it is unlikely that Mickey would let Lisa be easily convicted, doubts about her true intentions will linger. It is possible that Mickey will discover the truth before the trial concludes, potentially influencing the outcome of the case. It remains to be seen if Lisa Trammell is telling Mickey everything or if there is a hidden side to her that she has kept concealed. In the upcoming Part 2 of Season 2, viewers will learn how the gloves ended up in Lisa's house and whether Mickey can ultimately save her from conviction.
