Avila's new contract is the hardest of his career and he wants to get out of it at all costs. Emiliano gets in trouble. Ismael believes he has earned the credentials to join the elite group of hitmen.
Avila accepts Mr Moreira's proposal but realises the contract will be complicated because he knows the victim, a dangerous cop he tangled with ages ago. He must also take an apprentice under his wing.
Avila handles a trying assignment, but when things go awry, he has Ismael to thank for his life. Meanwhile, on the home front, Avila is under increasing pressure from both his wife and his mistress.
Avila is now officially the boss and along with his new title come fresh problems and responsibilities. The most pressing is an unresolved case that threatens the company's reputation for reliability.
Avila gets his first case as boss of the company. It looks simple and routine enough, but soon grows complicated and turns into a real headache. Ismael carries out his first assignment to the letter.

Detective Sanchez is hot on the trail of Emiliano and Ismael. Maria finds a huge wad of cash hidden in one of Avila's jackets. Avila hatches an infallible plan to kill the 'immortal', but can it work?
Maria uncovers a new deception and is determined to get to the bottom of it. Ismael aims to find Juliana before the police do, but Emiliano makes a mistake that leaves him in danger of getting caught.
Avila searches for Tamara, but can't shake off his wife. The police close the case of Juliana but Sanchez has a hunch that there's much more to the story and decides to track down Avila on his own.
Avila admits his adultery to his wife, and Maria listens in horror to her son explaining that he's a murderer. Sanchez keeps up his pressure on the family, forcing Emiliano to make a radical decision.
Out of patience with his latest client, Avila decides to take matters into his own hands. Sanchez closes in on Avila, who becomes both prey and pursuer, and the final piece of evidence to condemn him.
