After suffering a profound loss, a haunted young woman named Theresa (Kirsten Dunst) comes to the conclusion that the best way to cope with the anxiety she feels would be to ingest a powerful cannabinoid drug in order to escape her reality. 

From there, her life is filled with moments of suspended and altered consciousness as she continues to take drugs. She finds herself floating through the woods that she used to play in as a child, as she experiences isolation, paranoia, and grief in her dream-world state.
