In June 1985, Air India Flight 182 exploded off the coast of Ireland. It's considered the worst terror attack in Canadian history. Sujata Berry's 16-year-old brother, Sharad was on that flight. The shock of his horrific death morphed into an unshakeable grief. The family's sorrow was augmented with the lack of justice for victims' families — a flawed investigation, evidence lost and what Sujata says was "an unsatisfactory verdict." It's taken Sujata 40 years to chip away at her grief and try to understand what happened to her and her family. She explores love, loss and the grief that binds them in her documentary, All that Remains.
