Plot

When an undercover NARC and a Mexican mafia princess come to William for help, the girl's notorious father threatens to harm William's family if he doesn't stay away from her. Everything changes when William learns the NARC is in possession of stolen drugs, on the run from a dirty cop who wants them for himself.

The Cleaner contemplates love. Turns out he didn't really feel it because he didn't deserve it so "I could never really understand it." Profound words from William. And while the Cleaner converses with God, we see a young couple canoodling in bed before shooting up. True love, indeed. Cut to a highway. The young man, looking quite pale, speeds down the road. He calls the young woman named Anna, telling her to "wait for me." He then dials William -- but the cell call is cut off. "Damnit!" the young man yells before pounding the steering wheel. Will he be in time? Nope. Anna shoots up in a restroom, losing consciousness.

Moments later, the young man appears outside the garage, carrying an overdosed Anna. The Cleaner suggests the hospital. "No!" the young man called John insists. "No hospitals! No one can know!" So William takes the woman to the back room and performs mouth-to-mouth. Suddenly, Anna swims back into consciousness. "Welcome back," the Cleaner says. Later, John claims that "bad people" are looking for Anna. As long as her location is kept secret, everyone will be safe. The Cleaner is understandably skeptical. "You're using again," he tells John, who is apparently an old client.

Sometime later, Arnie arrives. "Boss," he says, "detective Baker is here." Baker explains that John is an undercover cop whose cover has been blown. Turns out Anna is the daughter of a Felix, a drug cartel bigwig. William denies any knowledge of Anna's whereabouts. "What I do is confidential," the Cleaner says. "I'm not saying that she's here, but like any other client, unless you're family, you need a court order." Baker sighs and then theorizes that John has been using again. William nods. He kind of already figured that one out.

The next morning, Akani notes that Anna has definitely been getting the "pure s***." William explains to his cocky assistant that Felix is no joke -- if she wants out, he won't hold it against her. "I don't have anywhere else to be," she quips. Meanwhile, Anna has awoken. She claims to have just "measured wrong" instead of deliberately overdosing. The Cleaner isn't buying it. Arnie enters with news: cartel thugs are outside. "I represent Felix Gonzalez," a particularly menacing cartel thug says. He then not-so-subtly threatens the Cleaner's family. But William doesn't budge. No one is to come inside.

Later, William demands that Baker explain just what the heck is going on. Turns out undercover John fell in love with Anna and the two planned to escape. "It's just a love story," Baker says. A love story with large quantities of illegal drugs, but still. The Cleaner kindly asks Melissa to leave town with the kids -- but she refuses. "Put your family first!" Melissa barks. "We are not shaping our lives around your work anymore ... we're not leaving." That's not good news because Anna warns that "everyone is going to die" as long as dad is angry. Great.

Night. John sneaks into the garage -- and is immediately tackled by William. "It's me!" John screams. Suddenly, we see that various cartel thugs are lurking outside. The Cleaner, John, Akani, Arnie and Anna jump in the truck and peel out. The cartel thugs pull their guns and FIRE -- but the Cleaner and co. get away ... for now. Later, they arrive at a safe house (read: an abandoned building) for a little R&R. William confronts Anna about her love for John. "Have you two ever spent a sober moment together?" he asks. The answer is clearly no. The Cleaner then asks Anna permission to speak with her father. "I don't know your father, but I know what he's feeling right now," William says. "He wants you to be safe, and what's so wrong with that?" Anna isn't amenable. She is clearly terrified of dear ol' dad -- and with good reason. Baker calls the Cleaner and explains that it isn't just "a love story," after all. Turns out John stole $12 million worth of drugs from Felix. Uh oh.

Baker arrives at the hideout and aggressively restrains John. William protests, but Baker won't listen. He drags John out the door. "The department needs John back!" the cop yells. Something tells us Baker STILL hasn't told William everything. After Baker leaves, Anna explains that the dirty cop arranged the entire deal. Baker was going to buy the drugs from John. "If Lawrence is dirty ..." Akani begins. "Then, who's watching my house?" the Cleaner finishes. Double uh oh. William jumps in the truck and RACES to his house. Thankfully, his family is safe. The Cleaner doesn't ask this time. He DEMANDS that Melissa, Ben and Lulu pack their bags and head immediately to a hotel. Melissa isn't happy but, then, when is she ever? Meanwhile, Anna seems touched that the Cleaner would put his family at risk to save her life. "Take me back home," she says. It's time to end this.

So William and Anna go to meet Felix at his cocaine assembly plant. "He saved my life," the girl tells her scary father. Says the Cleaner: "Your daughter needs help." Felix seems to consider the idea until William admits that he would encourage Anna to stay away from pops. "I'm not going to lock my doors," the Cleaner says. "You want to come after me, I can't stop you ... please, let me help your daughter." Felix responds by nodding quickly to a nearby thug, who BASHES William in the head with a pipe. Sometime later, William awakens in the garage. He is bloody and clearly in great pain. "Consider this your only warning," the particularly menacing cartel thug says. "If we ever see you again, you're a dead man." Soon after, William discovers John laying on the floor, bleeding. The former undercover cop has been shot in the gut. "Promise me you'll help her!" John croaks. He then hands William his car keys. The stolen drugs are in the truck. Then John croaks.

The plot twist devastates Anna, who decides to numb the pain with a liberal dose of the hard stuff cooked in a spoon. She swoons and passes out. Back at the garage, William wants to trade the drugs for Anna. "This goes against everything we do!" says Akani, noting that the deal would put drugs back on the street. "Don't save Anna! Save yourself!" Thankfully, it doesn't come to that. Felix suddenly appears carrying his overdosed daughter. The man is in tears with worry. "You did it before -- do it again," he says. "Tell her papa said 'goodbye.'" So William gets to keep the girl and the drugs. But its not over yet. The Cleaner meets Baker at the end of a dock. "I have something you want," William says. Baker admits to shooting John and demands the stash of cocaine. Naturally, the Cleaner empties the bag of drugs into the water. "No!" Baker screams. He pulls his gun on William, but ultimately can't bring himself to pull the trigger. Baker shuts his eyes as cops appear. He knows that his double-dealing days are over.

William concludes the episode by declaring that love of family is the most important thing (i.e. the best drug of all?). We have to imagine that God agrees.
