Based on the 2015 musical of the same name, the upcoming film sees Ben Platt reprise his role as the title character, “an anxious, isolated high schooler aching for understanding and belonging amid the chaos and cruelty of the social-media age.” At the recommendation of his therapist, Evan starts writing letters to himself to cope with his anxiety.
However, the letter is stolen by his fellow classmate Connor Murphy (Colton Ryan), who is also dealing with isolation and loneliness.
When Connor dies by suicide, his mother (Amy Adams) and stepfather (Danny Pino) mistakenly believe that he wrote the letter to Evan, who ultimately inserts himself into Connor’s past in a series of “inspiring, duplicitous and confrontational events”.
