Michael and Sam discover the location of Bill Johnson (Joe Kimble) by going through his trash and finding laundry bluing, a staple among spies to prevent snooping in trash. Michael returns to his loft to find Larry Sizemore (Tim Matheson), a former mentor of Michael's. Larry offers Michael $20,000, but then Michael raises it to $30,000, to kill a nurse named Jeannie (Amy Pietz) who stands to gain a lot of money when her ailing husband dies. Michael and Fiona track down Jeannie and inform her that Drew (Zachery Ty Bryan), her stepson, has placed out a bounty on her head. Michael protects Jeannie by faking her poisoning, aided by Fiona's new boyfriend, Campbell (Gary Weeks), a paramedic. Larry kills Drew to cover his tracks and leaves Miami. Michael and Sam follow Bill Johnson into a building and find out that Carla has been using Michael for tactical support for an unknown operation. Michael had collected the ID card for entry into the building (Episode 2), and the rifle that sniper Bill Johnson would be using. Michael also attends family counseling with his mother.

Hired by Fiona's boyfriend's friend Henry, Michael poses as a disgruntled bodyguard to thwart a kidnapping plot masterminded by a ruthless man named Lesher.

Michael prevents a man from committing suicide, whose son suffers from a heart condition. He had lost his savings in a scam after investing in a "miracle drug" for his son, so Michael decides to get him his money back.

Meanwhile, he has to deal with an explosion at his place and his brother in jail.

Michael is nearly killed when a powerful enemy sends a crew of cartel assassins after his entire team. Michael realizes that in order to protect the ones closest to him, he must eliminate the threat once and for all.
