Guided by mysterious crow calls, they wander through a desolate urban landscape until they reach a zone of passage and are spirited to an ancient forest, the Realm of the Birds.

However, one of the men has other plans for the birds. Though far from easy, the inter-species encounter will be illuminating for all.

Following the publication of A Thousand Plateaus, a work that marked a highpoint in his creative partnership with Gilles Deleuze, Félix Guattari began working on a screenplay for a science-fiction film, Un amour d’UIQ. This script, which preoccupied Guattari’s attention for seven years, represented a blueprint for a subversive popular cinema through an imagined hyper-intelligent infra-cellular life substance—“UIQ” (Universe Infra-quark)—capable of controlling global communications networks and plugging into the “desiring machines” of a community of squatters. After discovering the unpublished script, Paris-based artists and filmmakers Silvia Maglioni and Graeme Thomson initiated a multiform research project that culminates in their film essay In Search of UIQ, which takes on Guattari’s central quandary: how to give shape to a bodiless entity, seemingly without spatial or temporal limits.
