The Scottish Crime Drama That Keeps Viewers Hooked Until the Final Episode
With chilling murder investigations, forensic puzzles and secrets that reach deep into the past, Traces has earned praise from crime drama fans for its suspenseful storytelling and compelling performances. Set in Dundee, Scotland, the six-part series combines scientific investigation with deeply personal mysteries, creating a thriller that keeps audiences guessing across its two seasons.
First arriving on Alibi in 2019, the drama returned for a second season in 2022. Inspired in part by real-life forensic science research at the University of Dundee, Traces puts a team of women at the centre of disturbing cases that test their professional skills and personal lives.
Starring Molly Windsor, Martin Compston, Laura Fraser and Jennifer Spence, the series offers a mix of intricate mysteries, emotional revelations and high-stakes investigations.

What Is Traces About?
The first season introduces viewers to the Scottish Institute of Forensic Science (SIFA), where a young laboratory assistant discovers that a case study in her forensic science course may be connected to a tragedy in her own family.
Emma Hedges, played by Molly Windsor, returns to Scotland and takes a job at SIFA. While studying forensic science online, she comes across disturbing evidence linked to the unsolved murder of her mother, Marie.
What begins as an academic exercise soon becomes a deeply personal search for answers. As Emma investigates the case, long-hidden secrets begin to surface, forcing her to question the people around her and reconsider what she thought she knew about her past.
She is joined by Professor Sarah Gordon and Professor Kathy Torrence, whose forensic expertise proves vital as the women work to uncover the truth and bring a killer to justice.
The investigation places all three women under considerable pressure, blurring the line between their professional responsibilities and their personal involvement in the case.

Season 2 Raises the Stakes
The second season expands the story beyond a single murder investigation, introducing a series of terrifying bombings across Dundee.
As fear spreads throughout the city, the SIFA team must examine the evidence, identify the person responsible and help prevent further attacks. With the threat escalating, their scientific skills become essential to uncovering the truth before another incident occurs.
The change in direction gives Traces a broader sense of urgency while retaining the forensic investigations and character-driven drama that defined its first season.
