Keep reading to find out more…Written by Joe, here’s the logline: It’s nearly Christmas when an unexpected turn in their mother’s health thrusts four adult siblings, and their exasperating father, into chaos as they navigate messy family dynamics in the face of potential loss. But their quick-witted mother, June, orchestrates her decline on her own terms – with biting humor, blunt honesty, and a lot of love.

Along with starring in the movie, Goodbye June also marks Kate‘s directorial debut.

Goodbye June is hitting some theaters on December, and then will arrive on Netflix on December 24.
