该剧改编自真实事件。1988年12月21日，伦敦飞往纽约的泛美航空103号班机遭遇恐怖袭击，造成259名乘客和机组人员丧生，另有11名洛克比当地居民死亡。Jim Swire博士（科林·费尔斯 Colin Firth 饰）的女儿也在洛克比空难中遇难，他被提名为英国受害者家属的发言人，竭尽全力调查空难真相。
Sight Unseen, in partnership with Bell Media’s CTV, follows Tess Avery (Dolly Lewis, The Dutchman’s Pipe), a top homicide detective who is forced to quit the job she loves after nearly killing her partner and being diagnosed as clinically blind. Reluctant to accept help, Tess uses an assistance app and connects with Sunny Patel (Agam Darshi, DMZ), a professional seeing-eye guide and an agoraphobe living 3,000 miles away. After losing her vision, Tess is haunted by the unsolved cases she left behind. Using a hidden camera and earpiece, Sunny remotely steers Tess through life’s obstacles – and crimes – as the two challenge preconceptions about ability, trust and where to draw the line. Inspired by one of the co-creators’ experiences with sight loss, viewers join Tess and Sunny as they bring a fresh perspective to solving crime.
