Two mothers bond after their sons are killed in a mall bombing, but tensions arise when new evidence suggests one of the boys was responsible for the tragedy. When a massive explosion rocks a mall food court, the initial investigation suggests that a gas leak is to blame. As police barricade the scene, Maryam (Mahnoor Baloch) and Lea (Dendrie Taylor) arrive frantic, and seeking any evidence that their sons have survived the blast. Sadly, they did not, and the two mothers are left to mourn their devastating loss. Although on the surface Maryam and Lea couldn't be any more different, their grief bonds them when they are later summoned to the police station for further questioning by Inspector Kalkowitz (John Heard). Kalkowitz's methods of interrogation at first seem unnecessarily intrusive, but it's soon revealed that FBI agent Reese (Sharon Washington) has found evidence that a bomb was to blame. As a Pakistani-American, Maryam's son quickly emerges as the prime suspect, which leads to intense interrogation of both her and her husband Ali (Faran Tahir) -- who years prior had been arrested as a suspect in the 9/11 terror plot. Later, when the focus of the investigation shifts to Lea's bullied son, who had made a very public threat to his high-school tormentors, a deep divide begins to separate the two disparate mothers who once found strength in one another's support.
