After her untimely death, a scientist from Bangkok cryo-preserves his daughter's brain. Scandal swirls around the family as they struggle to grieve a child that, in their view, is suspended between death and reawakening.

A two-year-old girl from Bangkok, nicknamed "Einz" became the youngest person in the world to undergo cryo-preservation. After her death from brain cancer, her family stores her remains in an American lab. Her head and brain now rest inside a tank in Arizona. Hope Frozen follows the family who made this unorthodox decision. The girl's father, a laser scientist, yearns to give Einz the opportunity to experience a rebirth inside a regenerated body. He instils this dream inside his son, a 15-year-old whiz kid named Matrix, who wants to be a part of reviving his little sister. But what the boy later discovers will rattle the family's radical hope in science.—Bangkok ASEAN Film Festival

Refusing to accept her death as the end, they turn to cryonics to freeze their daughter's brain in the hope that she will one day live again. With remarkable access and intimacy, Wedel follows the parents and their surviving son on this extraordinary journey, objectively presenting their challenges and dilemmas; as practicing Buddhists who are also devotees of science, how to reconcile these conflicting beliefs? Ethical, philosophical and emotional questions abound. Can the dead come back to life? And should they? This is human nature in its purest form, as the parents are fighting for their child's survival.—London Film Festival
