The film involves many people who are trapped under a collapsed building after an Earthquake and are stuck amidst the rubble. It is not terribly intense, but if you are claustrophobic or have intense fears around natural disasters- it may be stressful for you. The characters converse intermittently, occasionally distressed and/or crying for help or in pain.
A man is smashed beneath concrete as a building collapses on him. We hear him gasping for air and taking his last breath
