Greenland follows a family in the Rocky Mountains of Colorado who reunite after a devastating event changed their lives 10 years ago. The piece opens with a dead deer being dropped onto the living room floor of the family cabin. Is it possible that this dead animal might just get up and leave? It's possible. But what's more probable is that Sissy, Ryan, Chappy, and Jazz will watch this animal rot and will become accustomed to, or perhaps even in love with, its stench.
