The Greek make a plan to build a large wooden horse and invade the city of Troy. Then they build the horse, having a door so warriors can get in. They hide in the horse and prepare to go in the Trojan walls.
All the other Greeks pretend to sail away. While hats happening, someone convinces the Trojans that the horse is a gift to the gods. The Trojans believe them.
The trojans bring in the horse. While some are skeptical, they still just go along with it. When night falls, the Greeks' plan is to get out of the horse and ransack the city.
Finally, it is the night. One of the greeks hold up a torch to signal the greeks on the ships to come back. With the army swarming from the beach, the robbing is about to start.
Everything is hectic. The greeks raid the city taking their treasures and helen back. They kill king Priam, and the Greeks have finally won the war.
They burn Troy, leaving only rubble. With The greeks having their hands full, they board the ships. After the long ten years of battle, they finally get to sail back home.
