Gisselle Shine aka Gissy is a 17-year-old student going on with her mundane school life. With just one more year of school ahead of her, Gissy looked forward to her last summer hols of school. She has to spend her whole summer hols with her cousin William Shine, a 10-year-old boy. During the very first day of her hols, things don’t go as planned for Gissy, and on top of that, she has an encounter with a stranger who claims to be a Galaxian, a member of a galactic organization from outer space. The Galaxian asks Gissy for help and Gissy fulfills it, hoping that her life would go back to normal, once she is done. Unfortunately, later she realizes that the truth isn’t what she thought it to be and sets on another rollercoaster to set it right.
