Ten years have passed since the fall of Troy. The surviving Greek warriors who destroyed that city have returned home.
All except Odysseus, whose wife, Penelope, and son, Telemachus, await him. Claiming that Odysseus is dead, a host of suitors have taken up residence in his home, eating up his wealth and trying to persuade Penelope to marry one of them.
Penelope steadfastly refuses. Odysseus, in fact, is alive. Odysseus has spent seven years as a captive of the nymph Calypso, the gods finally take pity on him and persuade her to set him free.
When he resumes his journey home, the sea god Poseidon sends a great storm to destroy his raft. Exhausted and near death, Odysseus and his men wash up on an island shore.
They are delayed by Polyphemus the Cyclops, the Lotus-eaters, the Sirens, the sorceress Circe, and other strange creatures.
