BritBox, the U.S. SVOD service run by ITV and BBC Studios, has offered the first glimpse of its debut original The Bletchley Circle: San Francisco.

The show moves to the Bay Area with two of the characters from the original British series — Mille, played by Rachel Stirling, and Jean, played by Julie Graham — traveling to the U.S. in 1956 to join forces with two U.S. code-breakers to tackle a string of new murder cases.

The Good Doctor’s Crystal Balint and The X-Files’ Ben Cotton have joined the cast of the eight-episode drama, which has just finished production and will launch next month. Zapped’s Chanelle Peloso and You, Me, Her’s Jennifer Spence also join the team of code-breakers.

The series is produced by Omnifilm Entertainment in association with Line of Duty producer World Productions for BritBox and ITV in the UK.

“With this new continuation, we have the chance to build on its amazing legacy and give its loyal fans an exciting new chapter,” BritBox president Soumya Sriraman said. “This series solidifies our commitment to our viewers and our brand identity as the No. 1 streaming home for all British content.”
