Brief summary of the opening scene

The opening scene starts off with a shot of a phone with a message from Linden, saying something along the lines of “it’s too much now, goodbye.” this then cuts to Jamie and shows the extreme shock in his face. He then checks find my iPhone to find the location of Linden, and starts running towards that location. When arrived it shows shots of all the items he has used associated with suicide, then slowly pans up to a shadowed figure hanging from a tree. Jamie then falls to his knees, and it fades into a 2 years before shot. After this a quick intro of two years before happens to establish what happened.
