The film uses both first-hand account and re-enactments to relay the story of the families’ marathon stay underground, scrambling for supplies and evading German authorities constantly looking for them.

The re-enactments are in here to take the film away from a mere ‘talking heads’ style documentary and to bring the interviews and stories to life. These segments are shot with a cinematic quality that enhances the film as a whole.
