Ramayana is a story of good succeeding over evil. All characters, good or bad, fight a personal battle between their desires to do good and their desires to follow the path of evil. Rama is a strong, wise, and powerful prince of Ayodya. He is marries the beautiful Sita. The demon Ravana kidnaps Sita and attempts to marry her. She refused to marry him. So Rama led a monkey army to the battle Ravana. Rama finally defeat Ravana with his golden arrow. Site was rescued, but Rama didn’t trust her anymore because she was leaving in the demons house for over a year. Site has to pass the fire trial to prove her purity and trust to Rama. Sita heart is purity and strength. Her love is enough to overpower the fire god's. Sita can't be murdered because she's very faithfully and good. One of the story message is that people have some amount of power to control their destiny.
Rama and Sita are married. One day when Site was alone Ravana picked her up against her wishes and carried her away.
Rama leads a monkey army across the sea to Lanka. They battle Ravana's forces for several days.
The struggle is dire. In the end, it all comes down to Rama's awesome archery expertise. He finally slays Ravana ending the skirmish.
When Rama saw Sita, he said, "I have defeated my enemy. This fight was not assumed for your sake; it was to keep the honor of my family. I can’t be with you anymore. For no man of honor can take back a beautiful woman who lived with Titan".
But Site is undaunted. To prove her faithfulness to Rama during captivity, she says she will undergo a fire ordeal. Lakshmana raises a fire and enters the flames. She is taken up by the fire god, unscathed, thus proving her purity.
Now reunited, Rama and Sita ruled Ayodhya. If Sita had not been captured by Ravan, Rama would have had no reason to fight Ravan. Sita was part of the plan to be captured, so Rama can prove that he can be king.
