Thony, a whip-smart Cambodian doctor, struggles to make ends meet as an undocumented worker after coming to the U.S. from the Philippines in search of a medical treatment for her ailing son. After witnessing a murder, Thony cleans the crime scene to stay alive, then begins living a double life, cleaning for a crime syndicate while doing what is necessary to save her son.

Thony attempts to sever ties with the crime syndicate when the FBI comes asking questions. But when her son’s health declines, she crosses a moral line, getting deeper involved with the syndicate. Meanwhile, things turn violent during a weapons exchange when inventory goes missing and Arman has 24 hours to find the thief.

Thony is given a dire ultimatum by Garrett that could compromise her son's access to medical treatment. Arman is tasked with collecting large "donations" for Hayak's daughter's wedding, calling into question his real role within the family. Meanwhile, a rift forms between Fiona and her son, Chris, when a secret is revealed that has major consequences for his future, sending Fiona into a spiral as she tries to find a solution.

When a party bus cleanup job takes a turn for the worse, and Garrett puts Thony in a threatening position, she must choose between her loyalty to Arman and saving Fiona from deportation. Meanwhile, after all his efforts to secure a new business for Hayak, Arman is blindsided when Hayak chooses his daughter over him.

Since their brush with ICE, Fiona and Thony’s relationship is strained, as a result of Thony’s lies. Meanwhile, Arman uses Thony’s relationship with Garrett to feed information to the FBI. Then, as Luca’s health declines, Thony must decide if she can work with Mother Donna, who may be a potential resource for a liver transplant for Luca, but at what cost to Thony.

Thony's marital issues are amplified as Marco begins asking tough questions about her methods of getting Luca life-saving treatments. Meanwhile, Arman is determined to make his way out from under Hayak, but Garrett is hell-bent on foiling his plans.

Thony enlists Arman’s help to get to Mexico for Luca’s transplant, but plans go dangerously off course when Hayak finds out Arman is lying to him. Thony finds herself in a desperate situation, forcing her to call upon both the former doctor and the newfound “gangsta” in herself.

Arman's fallout with Hayak has severe consequences for Thony, who must now find her way back home from Mexico with Luca. In hiding, Arman tries to help Thony get back, but it is Garrett who steps in to get Thony across the border where, upon re-entry, things aren't what they seem.

In need of a way out, Thony tries to make a deal with Garrett to save herself and help Arman; Loyalties are put to the test as families both unite and fall apart.
