Six-year-old Sam Geraghty is taken from his school. Much to the relief of his parents Anna and Joe, Sam is found unharmed hours later and the police arrest ex-schoolteacher, Simon Heywood. But this is far from an open and shut case as it turns out that Simon is Anna's ex-lover, and his neighbour and possible accomplice Angela has an intriguing connection to Joe. Soon Simon's psychiatrist and ally Dr Alex Klima, his lawyer Gina, and even Joe's best mate Mitch get pulled into the vortex where relationships become entangled and moral dilemmas abound about who really is at fault. And it's not a matter of who took Sam, but a question of why.
