In a continued effort to find Colleen McGrath (recurring guest star Audrey Marie Anderson), a missing young mother who had recently been recruited as a drug mule (someone who swallows pellets of illegal substances that are wrapped in condoms or latex gloves, travels to another country and then delivers the drugs), Samantha goes undercover as a woman with similar grim financial circumstances hoping to be approached by the same drug traffickers. Soon after Samantha takes a job at the retail outlet store where Colleen worked, Danny connects the outlet store's manager to another drug mule who was killed two years earlier. After getting the manager to reveal the identity of his boss, Samantha takes a job at the plant where the drug trafficker is seeking recruits. Once there, Samantha convinces Jack to let her go deeper undercover after she is recruited to be a heroin courier.

The team searches for Colleen McGrath (recurring guest star Audrey Marie Anderson), a struggling, young, single mother who vanishes after leaving her 3-year-old son in his baby-sitter's care. The detectives create a profile of a loving mother who, despite working two jobs as a housecleaner and a retail-outlet clerk, has been barely able to afford her motel room or the baby-sitter. The team must determine if Colleen has simply run away from her troubles. However, further revelations about Colleen's nervous demeanor on the day of her disappearance, her suspicious windfall the week prior, allegations of illegal activities in her motel room and the disclosure that she had suddenly felt uneasy about cleaning for her current employer, lead the team to question how clean a life she's been living--and if she's been victimized.
