I don't want to spoiler too many people :)
So,
SPOILER/CN
It's about a woman, who wakes up in a dark forest (a limbo so to say) and doesn't know where she is and what she's doing here. While walking down a path she finds some memories and tells her story again (husband is abusing her and beats her up several times). At the end of the path, she can decide if she wants to wake up from her coma again but has to live without him or stay in limbo to find him and stay there "forever together".
