When single mother of two, Alex, begins to see her son develop an unhealthy obsession with social media, vlogging and sinister 'mystery boxes' ordered from the dark web, she decides to take things into her own hands. But it seems moving to a lakeside community isn't enough to shrug off her son's fixations. Even with no internet access, the boxes keep arriving at Alex's door. Only now they contain familiar items. Items from Alex's life, her past and even from inside her house. Her son promises he is not responsible. So where are the boxes coming from? Who is sending them and what do they mean? And can the new community around her really help Alex before she loses her son forever?
