America’s favorite TV serial killer is back!

As his only confidant, he teaches Dexter a Code that’s designed to help him find and kill people who deserve to die—all while avoiding getting caught by law enforcement. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.
