This is Hachets farm house were he keeps the phone and medical bag. He lives out here because his job is to save people.
Some people live in the middle of no where so does Hachet. He can save people faster because he live close to them. It is much more helpful because it would take a regular ambulance a lot of time to get to the patients location.
Harvey is suffering chest pains. Even though Hachet knows Harvey is dead he cant stop helping him because the wife is giving him a look saying please save him. So Hachet keeps trying to save Harvey.
