As part of an inter)state emergency forest fire effort, Los Angeles firefighters Evan "Buck" Buckley, Eddie Diaz and Hen Wilson (from 9-1-1 LA) travel to Texas and meet Owen, TK and the rest of the first responders to assist in putting out a huge wild fire that is spreading out of control. Owen and Hen, who used a helicopter trying to save a teen who is badly wounded and disheartened, whom Judd manages to motivate loco parentis, inadvertently get trapped in a mine, where Owen's about the lava-killed paramedic whose funeral they miss due to this mission culminate. TK and Buck bond as they mount a rescue for Owen and discuss their home related problems. Eddie discovers Marjan's social media star status.
