The next numbers the Machine provides are for fourteen-year-old Malcolm Booker, and his eight-year-old sister, Tracie Booker, who are in foster care as their mother is incarcerated on a conviction for illegal firearms possession. Reese, who is tasked with finding them, quickly learns that they are the intended targets, as they stole $500,000 in drug money from the Brotherhood, a gang led by the unknown Dominic. Reese knows of the Brotherhood because he helped put in jail one of the gang's higher ups, Link, who is now out. The DEA is interested in the case, their head agent being Erica Lennox, who decides to work in conjunction with Reese as she knows there is a mole in the DEA working for the Brotherhood. When Reese and Lennox eventually find Malcolm and Tracie, they learn the reason why they stole the money. However, Malcolm has hidden the money and refuses to give it back. Reese and Lennox have to try and protect Malcolm and Tracie from the Brotherhood, all the while trying to get them to give up the money wherever Malcolm has it hidden, and discover the identity of the DEA mole. Shaw may be able to assist as she has one of the injured Brotherhood members, Mini, in unofficial custody; he who may buckle under the pressure of being in the gang. Meanwhile, Elias, who helps them stave off the angry Armenians in this drug war, can see that something in Finch and Reese's life has changed and he tries to find out exactly what has happened.
