The film follows a dramatic family affair which mainly centres around the wildly complicated relationship between Lina (Rose Williams) and her mother-in-law, Katherine (Famke Janssen), after the former marries the latter’s stepson, Jamie (Finn Cole).
But this is far from your average mother-in-law conflict. You see, when Lina was young, her mother died, with Katherine becoming her adopted mother.
As well as a plot full of twists and turns, Locked In also boasts a cast that may be familiar to many viewers, with its stars previously appearing in Peaky Blinders, Pushing Daisies and another huge Netflix franchise.

She is best known for appearing in period dramas such as Reign and Sanditon, as well as the recent film Mrs Harris Goes To Paris.
