Mary's growing dementia not only ends her teaching career, but also leads to her losing the family dog. The patience that has kept their marriage afloat for 39 years gives way to the stress as her husband suffers a heart attack.
Their adult children attempt to help out but it's difficult to accept that your parents will die one day-and that day might be soon.
Mary finds herself drawn to a specific place. And as strangers inexplicably tell her, she just needs to figure out where that is while she still can.
The family must choose between finding a new way to support themselves and helping Mary make one last salient memory while it's still possible. And they must do this while the sun burns out, flocks of birds fall dead from the sky, and buildings full of people disappear in an instant.
