After Mike loses Pia, her best friends Vicky and Zaza help pick up the pieces. But though Pia's gone, she left a plan. A list of instructions to hold Mike and her friends together. Just-engaged Zaza fears committing any further. Mum Vicky can't see a way past her kids and back to her career. While Mike just feels lost without Pia. When the list sends them to Peru - where sweltering rain forests and mountain treks take them to the brink - only Pia's instructions will guide the way. Did anyone say Walking On Sunshine was easy?
