In turn-of-the-century London, three nannies from drastically different backgrounds form a tight-knit bond that guides them through the good times and the bad times in this period miniseries starring Clare Wilkie, Victoria Smurfit, and Tabitha Wady. As the caretaker for the children of London's most elite families, headstrong East End girl Mattie (Wilkie) has struggled to build a solid career as a trusted nanny. On the heels of a disastrous romance with the son of a respected Yorkshire family, Hannah (Smurfit) arrives in London with little more than her young infant and a prayer. Though former farm girl Lydia (Wady) may be a bit naïve, her relative innocence doesn't stop her doing her best for her forward-thinking new employers. When fate brings these three nannies together, a bond forms between them that will help them navigate life's unpredictable twists while learning the true value of friendship.
