Inside the city Troilus, the Trojan King»s son, falls in love with Cressida, whose father has defected to the Greek camp. In an exchange of prisoners the couple are split – they believe forever. The honour of lovers and soldiers is tested as a fierce battle begins and heroes must prove their worth.
