When his mother passes, Aaron, a software programmer on the autism spectrum, struggles to cope with the change. He builds a life-like version of his childhood therapist, Emma, to talk to, and attends to his mother's last nursing client - a bitter old man named Ben. Both Ben and Emma push Aaron to adapt and navigate new and complex situations as their relationships evolve, including upgrades to Emma which make her more human than Aaron. As the connection with Ben grows and Emma's socialization push him beyond his own social abilities, Aaron must learn to adapt and change in life for the first time. A look at the role artificial intelligence can play in our society, and what it means to be human.
