Mike Weiss, a young lawyer from Houston battling addiction, partners with his longtime friend and law associate, Paul Danziger, in their firm, Danziger & Weiss. Their legal journey begins when they decide to represent Vicky Rogers, a dedicated ER nurse who contracts HIV after being accidentally pricked by a contaminated needle on the job. Vicky introduces them to a groundbreaking safety needle, invented by her family friend Jeffrey Dancort, which is designed to prevent such accidental needlesticks by being single-use only. With a deep sense of urgency, Vicky implores Mike and Paul to advocate for the product's adoption in hospitals. Tragically, Vicky succumbs to her illness, a loss that profoundly affects Mike.
Determined to honor Vicky’s memory, Mike investigates the case further and uncovers a dark web of healthcare corruption, revealing that no one will purchase the safety needle due to a massive conspiracy involving bribery within the pharmaceutical industry. Soon, the defense assembles a formidable team of heavyweight attorneys, including Nathaniel Price, which places increased pressure on the already financially strained law firm. As the battle intensifies, Mike's personal demons, including heavy drug use and feelings of isolation, begin to interfere with their professional efforts. He turns to sex therapy for solace and finds himself frequenting the company of prostitutes, a destructive cycle that ultimately hampers his career.
Despite these challenges, Mike, Paul, and Dancort garner support from Senator O'Reilly, though she issues an ultimatum to Mike: he must get clean. However, following a severe withdrawal that lands him in the hospital, the financial strain on their firm becomes unbearable. Just as momentum seems to stall, the Senator withdraws her support after United Medical Health Supplies exerts influence over her re-election, further complicating their already precarious situation. Meanwhile, Paul, now a new father, is drawn away from the fight, choosing to prioritize family over the case.
As tensions escalate, they meet with Nathaniel Price, who proposes a settlement, igniting a fierce disagreement between Mike and Paul. Mike is determined to take the case to trial and strive for justice, while Paul asserts that their financial limitations make it impossible to proceed. In a pivotal moment, Mike encounters a former employee from Thompson Needle Manufacturers, a friend of Vicky's, who inspires him to continue fighting for those affected by unsafe needles, which can lead to the spread of AIDS and hepatitis. He vows to find new clients and advocates for hospital workers facing similar dangers. Sadly, the following day, Mike's struggles culminate in tragedy when Paul discovers him dead from a drug overdose.
At the settlement conference, Paul surprises everyone by walking in with renowned personal injury attorney Mark Lanier as they reject the settlement offer and assert their readiness to fight in court. The film concludes with the revelation that in 2004, Attorney Lanier successfully reached a settlement exceeding $150 million against one of the largest medical supply companies in the nation, prompting widespread use of safety needles in hospitals across the United States and ensuring that countless lives may be saved from the dangers of contaminated needles.
