In All of M, the high school prom becomes the vehicle to examine the role of social ritual in forming male identity and the physical trappings that enable sites of male homosocial belonging. The prom is understood as a coming-of-age event, one where adolescents dress up and perform as adults for one night, potentially marking the transition from one stage of life to another. In All of M, a group of high school seniors and adult men are brought together to enact a different version of the prom. For the adults, they recall their memories of the event while the teenagers express their hopes for the night. Their participation in this re-performance speaks to the anxieties tied to normative gender expression, while also pointing to the possibilities for re-imagining this ritual.
