Set in the fleeting era of dail-up and away messages, 15-year-old Sam (Autumn Best) embarks on a road trip with her older sister Dylan (Zoe Colletti) to meet the boy she's fallen for in a chatroom. But as the detours pile up, the sisters confront shifting identities and deeper truths: Dylan chases love through reinvention, while Sam wrestles with the courage to be seen- disability and all. BRB is a tender, darkly funny ode to early internet girlhood, complicated sisterhood, and what it means to be both too visible and unseen at the same time.
