Sienna and Declan are young high-profile NYC executives with an opaque marriage. Neither closed nor open, their mutual arrangement has been left to a laissez-faire interpretation. The rules are simple: never bring a lover to their home, and never fall in love with their affairs. Sienna feels trapped by the own rules she agreed to with Declan when she realizes shes fallen in love with her best friend from college. What follows is an affair of the heart and mind, their permitted sexual lifestyle against the unsanctioned emotional infidelity. Sienna must choose between emotional stability and marital security versus passion and excitement. Through an Opaque Window takes a solid view through the open windows of marital life, looking at what happens when we leave our lives ajar.
