'Stone Arabia' delves deep into the complex tapestries of family bonds and solitary artistic pursuit. In Los Angeles of the late '70s and '80s, siblings Denise and Nik Kranis form an enduring connection. Nik, a reclusive musician, creates prolifically yet shuns the public eye, zealously recording his works only for himself and most loyally, his sister. As their mother grapples with the fog of dementia and news of global and personal tragedies abound, Denise stands as a pillar of resilience. The dynamics shift dramatically when Denise's daughter, Ada, decides to bring Nik's shadowed existence to light through film, probing into the fragile nature of memory, creation, and the threads that hold a family together.
