Plot and Story - What's the difference?

This is my understanding of what I gleaned from the various confusing resources on internet. You are free to form your own conclusion.

Let me give an example from 'Aspects of the novel' by Somerset Maugham to explain it. (I have not read the book. I have just read from a site which cites the book)

The king died. Then the queen died. --example of story
The king died and then the queen died of grief -- example of plot.

An Indian example would be

Ravana abducted Sita. Rama took the help of Sugriva and invaded Lanka. They killed Ravana and brought back Sita -- Example of Story.
Ravana abducted Sita because he fell for her beauty. Rama while searching for Sita met Sugriva. He pledged his support to sugriva against his brother Vaali if he would help in finding Sita. Rama killed Vaali and Sugriva became the king. Sugriva's army fanned across the country in search of Sita. Hanuman found Sita. Rama and the monkey army invaded Lanka and killed Ravana and brought home Sita. -- Example of plot.

Well, what is the difference between plot and story.
In a story, we talk about the events that happen in chronological order. We focus on what happens after what.
In a plot, we talk about why the events happen. Why did Ravana abduct Sita? Why did Rama help Sugriva? We focus on what thrusts the story forward.
This is the basic difference.

Story comes first. Then comes plot. Always.
An absorbing plot will make an ordinary story a good read. But not a great read. For that, you need to work on the story.
