Melina Mercouri plays Maya, a jet-setting Greek actress who returns to her homeland to undertake the role of Medea. Searching for inspiration and clues as to how a mother could kill the children she loves, Maya discovers Brenda (Ellen Burstyn), a bible-spouting American woman serving time in an Athens prison for that very crime.

This expansive Greek drama follows a troupe of theater actors as they perform around their country during World War II. While the production that they put on is entitled "Golfo the Shepherdess," the thespians end up echoing scenes from classic Greek tales in their own lives, as Elektra plots revenge on her mother for the death of her father, and seeks help from her brother, Orestes, a young anti-fascist rebel.
