What do you do when you lose the only thing that you truly care for?
Ethan Willis is a confused 18 year old who struggles with the uncertainties of life and has just embarked on a quest to find his elder sister, Charlotte, who disappeared whilst travelling in South East Asia. Ethan admires and idolises his sister for her spontaneity, individualism and worldly understanding. His quest to locate her throws him into the backpacking world and, following what could be his sister's ghost, he is taken on a journey through the countryside of Cambodia, into the remotest parts of Laos and finally to the party islands of Thailand.
When Ethan finds his sister's journal by chance, he traces her footsteps. The travel journal, along with flashbacks to their childhood, reveals Charlotte's nature and her relationship with Ethan, taking the young man on an existential journey as he is led to address many of his questions about meaning, truth and beauty.
With the help of a Elodie, a fragile and complex girl with whom he has developed a meaningful relationship, and his own growing sense of self-esteem, Ethan begins to question his relationship with his sister and why she disappeared. When he finally learns of a place in which he might be able to locate his sister, will he be ready to find her?
