Lucy Letby was a young neonatal nurse when she began at Countess of Chester Hospital in 2012. Her whole career focused on the care of the youngest and most vulnerable patients. However, in subsequent years, the hospital saw an unexplained rise in infant mortalities and collapses, and all the cases had one thing in common: Lucy.

This documentary shows footage of Lucy on the day that she is first taken in for questioning, the police coming to her home and rousing her from bed to come with them. We see her interviews with the police, her reluctant words of denial at what she is accused of. We also see interviews with parents of the children she murdered while they were in her care—through insulin poisoning or by introducing air into their bloodstream causing embolisms.
It’s a reminder that looking innocent and being young can be a deadly cover for vile acts. Lucy was sentenced in 2020 and will spend her life in prison. Unsettling and infuriating, this is just the type of watch to make you wary of those who are supposed to care for us. Just remember that most caregivers are in the field to do no harm, despite cases like Lucy’s. (92 min.) ∆
