James Cole和Cassandra Railly将回到他们从未去过的时代完成最后的关键任务。根据传言，只有一件武器能彻底阻止「目击者」（现在Olivia取代了Athan的位置），这是他们唯一的希望。但是要想赢得这场战斗，拯救时间本身，他们必须做出终极牺牲。另一方面，Cole的母亲……可能会给他带来麻烦。
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.
