Senior C++ engineer Bear Bigbirdtrup's idyllic family life changed forever as soon as he heard his son's first word: 'NaN'. The seed of doubt has been planted. Few weeks later Bear is convinced his wife has been cheating.

Bear's wife, who is also interested in obscure forms of communication, denies allegations. Friends and relatives are worried about the state of the family, especially in the context of inheritance. While nothing has been decided, Bear's position is that his marriage is basically void and there is no return.

Child's future is undefined at this moment.
