Filipino-American high school student Ben works in a comic book shop to earn money to pay his way into Cal Arts. His father, a postman, is determined that his son, who has won a pre-med scholarship to UCLA, will become a doctor. The eighteenth birthday party of Ben's sister, Rose, sets off a comedic and touching series of events and family struggles that will in turn determine young Ben's future.

世间万物各有大小。仰望浩瀚星空，地球不过是沧海一粟；对于虫蚁，人类又如同巨人，遮天蔽日。宇宙是如何决定一切事物的大小的？万物的大小是否重要？本片带着这些问题，大开脑洞，进行了一系列无法实际操作的思维实验：在木星那么大的地球上生活会是什么样？我们如果变成巨人，或者是蚂蚁一样大又会有什么变化？还有我们习以为常的太阳，把它放大或缩小一些对我们将产生什么影响？在两期节目中，我们将把这些天马行空的幻想用科学手法进行模拟，用科学的分析解释万物大小的重要之处，极具趣味性。
