Dexter Season 3

Dexter kills a suspect, but isn't sure of his crime. His impulsive actions in pursuit of justice could cost an innocent man his life. Such actions lead to a series of chain changes in the lives of Dexter and those around him. To add insult to injury, another Assistant District Attorney, Miguel Vega, is on the hunt for Dexter. The third season will introduce some new characters, including Joey Quinn, a lovable policeman; and Ruben, Miguel's brother, who will assist Miguel and his wife Isabel.
