A gripping blend of suspense and family turmoil powers Under A Dark Sun, set against the rural expanse of a flower farm. Alba Mazier, burdened by her past, accepts a seemingly innocent job offer, only to get trapped in a fatal conspiracy following the murder of Arnaud Lasserre.

The sharp character contrasts, especially between Alba and the unruffled Beatrice, increase the escalating tension.

The flawless cast of Under A Dark Sun justifies the characters and their portrayal.
