It will focus on a local vicar (Tennant), a man on death row in the United States (Tucci), a journalist (West) and a maths teacher (Wells) as it follows how all their stories intertwine.
Very little has been given away in terms of plot details so far and it remains to be seen how all these disparate people will connect.
It will consist of four episodes and is a co-production between the BBC and Netflix, meaning it will be shown internationally on the streaming platform at a later date.
When will Inside Man be on TV?
The first episode of Inside Man will air at 9 pm on BBC One on Monday, September 26 with the second episode following a day later at the same time.
After that, the third and fourth episodes will air on October 3 and 4 respectively.
