'In Vitro' is an otherworldly rumination on memory, history, place and identity. Set in Bethlehem decades after an ecological-disaster, the dying founder of a subterranean orchard is engaged in a dialogue with her young successor, who was born underground and has never seen the town she's destined to replant and repopulate. Inherited trauma, exile and collective memory are central themes.
