Avila's regular job is selling insurance. He is married to Maria and they have a teenage son, Emiliano. Harmless enough from a distance, the man buried in this disguise conceals a ruthlessly efficient executioner.

Sr. Moreira, Avila's boss, orders a new contract kill which will prove to be the hardest of his entire career. By completing the task, Avila will be offered an opportunity that will change his life.

Avila accepts Sr. Moreira's proposal of taking over the business. This includes mentoring the psychotic and young Ismael.

Sr. Avila struggles with his first case as boss, while Ismael rises to the occasion. Emiliano pursues Juliana, who rejects him with unexpected consequences. Avila desperately searches for Maggie, but soon realizes her problems will affect Ivan and Ana.
