The creative team behind Downton Abbey reunited for this historical drama, set a century before the Crawleys we know and love. At one fateful ball in 1815, a newly wealthy family and a family of old aristocrats are forever connected. Twenty-six years later, when the families both are settled in the elite neighbourhood of Belgravia, the repercussions of that night lead them back into each other's lives. This time, there is a new generation of young heirs and heiresses, whose lives, loves, and inheritances crisscross in a tangled web of romances and enmities, with dangerous results.
