When the flamboyant Henry Paget arrives in 1890s North Wales to claim his aristocratic inheritance, his theatrical flair and defiant eccentricities send shockwaves through the upper-class elite, much to the amusement of the local townspeople. Alongside his spirited cousin, Lily, and loyal butler, Gelert, Henry tries to carve out his own identity as the Fifth Marquess, navigating suffocating traditions, scheming relatives, and the long shadow cast by his estranged father.

Jack has been married to Maggie for over half his life. He works as a Hand Raker on the mussel beds in North Wales alongside his younger brother, Dyfan, and Dyfan’s three sons. Jack has always assumed that his own boy, Tom, will join the family business on leaving school but Tom’s resistance to follow in his footsteps creates familial tension. Tensions are further inflamed by the arrival of an itinerant deckhand, Daniel, who makes known his feelings for Jack. In this remote, rural community where life revolves around Church and fishery, Jack is faced with an impossible dilemma. On The Sea is a beautiful, sensual and at times, tragic exploration of masculinity, place and desire.
