 Oscar Vazquez (Carlos PenaVega) goes to an American Forces Career Center to enlist into the U.S. Army; while he is waiting for his interview, he sees a video announcement and brochures about a Marine Underwater Robotics Competition, an event sponsored by NASA and the United States Armed Forces.Although he distinguishes himself as part of the Carl Hayden High School Junior Reserve Officer Training Corps, he is forbidden to join because of his status as an undocumented immigrant; he is recommended not to present himself to any government office to avoid being reported to the Immigration and Customs Enforcement (ICE) agency.Vazquez lies to his mother about his progress in the Army; looking for another way to move ahead in life, he investigates the Underwater Robotics Competition.
