One of Sinjai's most challenging and impactful roles was Mathusorn in the 1994 drama Lah (ล่าLaThai; meaning "Hunt" or "Revenge"), broadcast on Channel 5. In this role, she portrayed a mother who, along with her daughter, suffers severe physical and psychological abuse, including being raped by seven criminals. When the legal system fails to deliver justice, Mathusorn takes matters into her own hands, becoming a vigilante who systematically murders the seven perpetrators. The drama was considered groundbreaking and intensely dark for its time, with its themes of stress and despair. Sinjai immersed herself so deeply in the character that she found it difficult to detach, reportedly seeking guidance from a nun to break free from the role's emotional toll. Her powerful performance earned her the Best Actress award at the Golden Television Awards that year, a moment met with a standing ovation from the audience and fellow nominees.
