Ellen lives in the city with her husband and young toddler.
One day when the den window is open she notices a window across the way in a different apartment building. It is painted bright yellow, and had a flower box of blood red roses hanging from the sill.

Inside the apartment is a woman and her boyfriend, both gorgeously young, in the prime of their lives. Ellen becomes jealous and begins watching them, willing the two to break up, yet they never did.

But Ellen, even though she has no business there, watched the two until something unexpected happened. . .

She was the woman at the window, and she became part of the couple's life, even though they did not know.

She saw everything.
