Acorn TV’s sitcom The Other One is about what happens when you discover your dead Dad had a secret family and you now have a brand-new sister. The witty ensemble comedy follows two half-sisters both named Catherine Walcott, who do not know the other existed until after the untimely death of their father – and it’s also about their mothers, who were his wife and longtime mistress. Originally premiered on BBC One in June 2020, this engaging comedy follows the four leading women who adjust to living with their new-found sisters and sort-of step-mums. The Other One premieres exclusively as an Acorn TV Original series in the U.S. and Canada on Acorn TV as a binge on Monday, August 10, and stars Siobhan Finneran, Rebecca Front, Lauren Socha, Ellie White, and Amit Shah.   There are also multi-episode guest stars Caroline Quentin, Stephen Tompkinson, Neil Pearson, and Simon Greenal.

For Cathy Walcott (White), her life is turned upside down when she learns that her recently-deceased father, Colin had a secret love child living 13 miles away in a neighboring town and is only five days younger – her half-sister, Cat (Socha) who has the same birth name, Catherine Walcott (a smart move from the dad when you’ve got a secret daughter.) Incidentally, both Catherines have always wanted a sister, but they have very little in common: Cathy has a fiancé and a pension and is a successful, yet uptight, re-insurance agent, while Cat is single, a food delivery truck driver, has a pay-as-you-go phone and is more outgoing and bubbly.  Now that the two are thrown together, Cat wants to spend as much time with Cathy as possible to make up for the last 28 years, but Cathy has a wedding to plan. Nonetheless, they end up forging an unlikely friendship during this difficult time – Cathy is forced to take compassionate leave at her job because of stress over her father’s passing and the upcoming nuptials and Cat cheers her up with a party. They reminisce fondly over special moments with their father, either his favorite songs (a fun car singalong of Supertramp’s “Goodbye Stranger” ensues in the series premiere), as well as childhood toys and nicknames he had given them.

Their mothers are the opposite – though they have an equally rough time adjusting to a new normal without Colin in their lives. Wife Tess Walcott (Front) vents about her husband’s philandering during the funeral eulogy and is eager to destroy his possessions, but once she’s cooled off, struggles to move on by joining dating apps and taking a Nordic Walking class. Colin’s longtime mistress of 30 years, Marilyn (Finneran) is more playful and free-spirited and is accepting of her role in Colin’s life because of her strong love for him, though he would only visit her and Cat once a week for nearly three decades.

Created and written by Holly Walsh (Motherland, Dead Boss) and Pippa Brown (Psychobitches, Bad Education), this warmhearted series captures these four multidimensional women from different walks of life dealing with Colin’s death together – from finding his will to debating over where to sprinkle his ashes to boxing all his things to prepare to sell the house.  With a vibrant, eclectic pop music soundtrack featuring modern and classic tunes, The Other One brims with contagious energy, Cat’s brightly-hued wardrobe and the lively, charismatic and at times saucy humor of four women who all share a common purpose: finding happiness, comfort, and love in the company of newly-discovered family.
