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.

A corpse is found at Anna's home, and she must explain the criminal investigator how she spent the night. And one story leads to another.
