Eesa and Mokhtar, miners, get into a fight. Eesa pushes Mokhtar, and makes him fall. Mokhtar's oxygen tank starts leaking, without anyone noticing. Eesa discovers methane gas and saves some people, but Mokhtar dies due to an empty tank. Eesa, torn, faces a choice: lie and become a hero or confess everything and carry the weight of killing Mokhtar.
