In TROY: FALL OF A CITY, 20-year-old Paris (Louis Hunter) is a strapping young herdsman who's discovered to be the king of Troy's son, previously thought to be dead. Welcomed back to the palace as a prince, he's sent on his first diplomatic mission to neighboring Sparta, where he falls instantly in love with Helen (Bella Dayne), the wife of the Spartan king, Menelaus (Jonas Armstrong). When Paris secretly brings Helen back with him to Troy, it is seen as an act of war, and Menelaus enlists the aid of his warrior brother Agamemnon (Johnny Harris) and his armies to get Helen back.
