When primary school teacher Gemma Hillman goes missing, DC Martin Young and his surveillance partner Stella arrive to set up their surveillance post in the home of single mum Zoe and her daughter Caitlin. They are watching Gemma’s boyfriend Greg Sullivan, who is prime suspect in Gemma’s disappearance. As Martin watches the street, he uncovers a lot more than Greg’s dirty laundry when it turns out everyone living on the street is hiding their own secrets. Zoe’s initial coldness towards Martin thaws when he shows affection and guidance to Caitlin, stirring up displaced paternal yearnings that he’s missing out on with his own son, Max. And when Martin has to leave his post to help his son in need, Zoe covers for his transgression and they form an illicit bond. After an emotional candlelit vigil for Gemma, all eyes are back on the street as Martin watches on with horror as an unexpected dilemma unfolds before him.
