From IMDB:

In 1918, with her husband working in the War office – and subsequently leaving the family – devoted mother Annie Lee takes her step-daughters and her own children to live in the idyllic Gloucestershire countryside, the youngest being the sickly Laurie, known as Loll. Here they witness two feuding matrons, Granny Trill and Granny Wallon and shelter a young army deserter hiding in the woods until his capture. At school Loll and his classmates are terrorized by the formidable teacher Crabby until hulking Spadge Hopkins literally puts her in her place. Far more important to Loll’s schooldays are the captivating Burdock sisters, Jo and Rosie, and, as he grows into adolescence and beyond, eventually leaving home to seek his fortune, he samples the delights of cider with Rosie.

From Acorn TV:

This beautifully shot, elegiac drama is a coming-of-age story set in a remote English valley post-WWI. Raised by his kindly mother (Samantha Morton, In America) among a pack of siblings, Laurie Lee experiences the wonders of love and friendship but also the brutality of loss and death. “Brilliant performances underpin a lyrical, languid, and poetic adaptation [of Lee’s memoir]” -The Telegraph.

From Wikipedia:

Cider with Rosie is a 1959 book by Laurie Lee (published in the US as Edge of Day: Boyhood in the West of England, 1960). It is the first book of a trilogy that continues with As I Walked Out One Midsummer Morning (1969) and A Moment of War (1991). It has sold over six million copies worldwide.

From Acorn TV you can stream this heart-warming 89 minute film.

Annie Lee, the mother, is played by Samantha Morton (Alpha in the 2019 The Walking Dead).  Granny Trill is played by Annette Crosbie (Clarice Millgrove in  Call the Midwife) whose face was immediately familiar to me even though at the time of filming she was 81 years old.
