[2] The film follows the daily operations of a group of volunteer rescue workers of the Syria Civil Defence, also known as the White Helmets.

[7] Von Einsiedel said he first became aware of the Syria Civil Defence when he and producer Joanna Natasegara were shown grainy YouTube footage of an infant being dug out from beneath rubble in the aftermath of a bombing.

[8] After seeing the footage, Von Einsiedel reached out to the Mayday Rescue Foundation, which provides support to the White Helmets, to ask to join volunteers as they trained in Turkey.

Shortly thereafter, Von Einsiedel commissioned Khaleed Khateeb, a volunteer for the Syrian Civil Defense who had been informally documenting rescue missions since 2013, to be the film's videographer.

[10] "Crashing Down", an unreleased Plastic Beach track by Gorillaz featuring the Syrian National Orchestra for Arabic Music, is played during the credits.
