Twenty years ago, Rick Murray left town after his father was arrested by the State Police for trying to murder Rick’s best friend, Dan Reilly. Now Rick is back in Exeter. Dan must grapple with Rick’s return and the memories that come with him. As childhood memories run headlong into the reality of what happened that summer, both men must adjust to the idea that things weren’t as simple as they seemed back then. All That Is Necessary explores the collision between past and present, between memory and reality, and between two former friends whose lives changed one summer more than twenty years ago.
