Comparing how and where to watch

We're all different; and so are the ways we watch movies.

Ever wondered why some titles are 'buy only' and others not. It is down to 'release windows'. Each film goes through each window, like we go through school years.

The Sibling Rule

Suzanne has a well-buried secret. When she runs into her childhood estranged best friend, Valerie, she discovers their daughters have also become best friends. Both women fear how their divorces have effected their children, and when Suzanne discovers the kids can no longer stay in the same school together, she wants to stop her daughter from having one more loss.

When Suzanne finds out the school has a “Sibling Rule” which guarantees that siblings can attend the same school even if there is no space for them, Suzanne impulsively asks Valerie to marry her. All goes well at first… until the fake marriage begins to feel a bit too real.
