In the summer of 2014, a bomb decimates a British nightclub, killing 55 people and injuring hundreds more. Among the victims is 28-year-old Avery Adams, who is pulled from the debris but succumbs to his injuries and dies a week later in hospital with his close friend Gabriel Rhimes by his side. A year on, Gabriel is in therapy in an attempt to get his life on track following the events of the disaster and the impact that losing Avery has had on him. He's forced to confront startling truths about himself, his relationships, and his own identity as he recalls the life he and Avery built together.
