Set against the historic 1916 miners' strike on the Greek island of Serifos, the series blends fiction with real events from a landmark moment in the labor movement. Perseas, the son of a miner killed in the island's dangerous tunnels, grows up under the guidance of his strong and unconventional mother, Katerineta, who teaches him to face life with courage and dignity. Forced by circumstance to follow his father's path, Perseas begins working in the harsh and perilous mines from dawn until dusk, struggling to survive in the island's unforgiving landscape. Amid exhausting labor and growing tensions between workers and mine owners, Perseas falls in love with Andromeda, the daughter of a man who stands against him and the miners' cause. Their relationship unfolds alongside the rising unrest of the workers, whose fight for fair treatment and humane working conditions becomes a defining moment in their lives and in the broader history of social struggle.
