Forensics expert Joe Donovan uses science to snare killers - and save himself.

Award-winning actor Tom Conti (Shirley Valentine; Reuben, Reuben) stars as Joe Donovan, an accomplished but troubled criminologist who returns from a mental breakdown to lead Manchester's crack Forensic Investigations Unit. Called in to consult on a murder case that suspiciously resembles the one that drove him into near madness years ago, Donovan redeems his reputation and rediscovers his devotion to the job. Yet his professional dedication bleeds into the personal life, alienating his wife (Samantha Bond, Die Another Day, Tomorrow Never Dies) but appealing to his son (Ryan Cartwright, The Grimleys), who wants to follow in his father's footsteps.

Packed with fascinating procedural details and wickedly captivating plot twists, every episode of DNA delivers edge-of-your-seat suspense. But with its complex characterizations, it also explores the human dimension of the scientists who solve crimes.
