The first feature from Benjamin Cleary (after the Oscar-winning short film Stutterer) is a stylish, near-future-set story of love and loss, in which loss can be avoided thanks to radical new technological advances. Mahershala Ali plays Cameron, a husband and father who decides to protect his loved ones from the truth about his terminal diagnosis by signing up for an experimental programme. An alternative Cameron is created; all of his memories are uploaded, and this new, disease-free version of himself is seamlessly introduced into his life.

Ali is tremendous in a dual role that takes in everything from a beguiling meet-cute with his future wife (Naomie Harris) to a third act consumed by grief and doubt about whether he did the best thing for his family after all.
