The great man himself. Ulysses, his son Telemachus and his friends left the base at Troy for what should have been a routine journey to Earth.
However the gods had other plans. His son was captured and held prisoner by the disciples of the Cyclops. The only way Ulysses could free him was by killing the Cyclops and thereby incurring the wrath of the gods.
The punishment meted out to Ulysses was to have his companions put into a deep sleep and his navigation system wiped of the route back to Earth.
Ulysses has to use all his cunning to survive the trials set by Zeus, find the route back to Earth and lift the curse befallen his companions.
