Grace invites Alice and Megan to spend Easter in her house in Lanzarote. The girls are accidentally left home-alone for two days in the house. It’s fun at first, until they become trapped on an upstairs balcony and spend a long cold night and day waiting to be rescued! Meanwhile Melissa is still unhappy at boarding school. Alice wants to help her to get back to their school, but Megan sees this as a betrayal. Tension mounts between the two girls, until Megan gives in and agrees to help. In the end, Melissa comes back, and Megan realises that she is confident enough to stand up to her.
