Inspired by his mother and all those who braved the leap to Britain in search of a new life, Henry has written a "spirited, moving, funny and utterly heartfelt" series that celebrates immigration, community and Black womanhood.

Opening in 1957, the clip introduces Rochelle Neil's Leah and Saffron Coomber's Chantrelle, two gregarious sisters who are seen persuading Yazmin Belo's Hosanna to join them in emigrating from Jamaica to Britain.  

The upright Hosanna is working as a trainee nurse, but the sisters manage to convince her to quit her job and board the cruise ship. The sisters themselves have been encouraged by their older brother Aston (Javone Prince), who has asked them to bring him a potential wife from home, and they reckon Hosanna could be the perfect match.

But upon arrival, Hosanna is a little let down by the real-life version of the man she'd seen in their photograph. Turning to Chantrelle, she says, "how long ago did he take that photograph? He seems to have sagged a little bit in the middle."

They all have their own reasons for upping and leaving Clarendon, Jamaica, but they soon discover that rainy Blighty is not all it's cracked up to be.

The series also stars Bobby Gordon as the sisters' new factory-worker colleague Shelton, and Arthur Darvill and Beth Hayes as Chantrelle's employers, who demand a lot from her as the live-in Nanny for their three children.

Three Little Birds was filmed in The Midlands, where Charles McDougall, Yero Timi Biu and Darcia Martin directed two episodes each.

The six-part series will air on ITV and ITVX later in October 2023.
