An eleven-year-old boy named Odysseus lives on the Greek island of Cyprus. On a visit to the Museum, he buys a small replica of a statue of Polyphemus, the Cyclops from ancient Greek mythology, and takes it home with him. That night he dreams that he is the ancient hero Odysseus caught in a storm at sea - on a deserted island he encounters a huge Cyclops in a cave. The next day Odysseus' school-friends Sophocles and Chloe come to his house to play. They accidentally bring the little statuette of the Cyclops to life, which leads them into fantastic adventures.
