April's longing for excitement and adventure leads her to a moment of epiphany: she wants to leave New Canaan and live abroad. Her desire is met with resistance from Frank, who's invested in maintaining their carefully constructed lifestyle. As their differences intensify, the cracks in their relationship begin to widen, and the facade of their perfect marriage crumbles.

However, as the story unfolds, we see that beneath the facade of a perfect marriage, the Wheelers are suffering. They're trapped in a stifling environment, suffocated by the monotony and materialism of suburban life. April feels suffocated by the constraints of domesticity, while Frank is increasingly disillusioned with his role in the corporate world.
