Walter White gets more than he bargained for when he realizes the notebook Saul gave him is actually a murderous weapon with a complicated - and deadly - history.

Walter White has many problems. Many. But thankfully, there are people like Saul who provide solutions to those problems. In this case, a solution in the form of a innocent-looking black notebook. Except there's another problem that seems bigger than the others. The original owner wants his book back.
