17 peo­p­le died at the school shoo­ting in Parkland, many others were hurt and trau­ma­ti­zed. The anger of the sur­vi­vors for­med the „March for our lives“-movement. For 18 months Kim A. Snyder wat­ched the cen­tral prot­ago­nists behind it. Their poli­ti­cal acti­vism is enri­ched with adre­na­line and emo­ti­ons.  The group of teen­agers demand effec­ti­ve actions to con­trol the pri­va­te pos­se­si­ons of fire­arms. Within a short time peri­od the local initia­ti­ve not only grows into one of the big­gest pro­test actions in US histo­ry, but a world­wi­de mass movement.
