Summer 1996. Days after finishing their national college entrance exams, teenagers Simao, Awai and Qiming crashed their car at dawn following a night out in Beihai - with passengers An'an and Xiaomei. Simao, the driver, hovered near death in ICU for three months while his grandmother and traumatized friends kept vigil. Unbeknownst to the comatose youth, two life-altering events occurred that summer: his long-absent mother visited secretly, and his college acceptance letter arrived. This coming-of-age story traces the trio's journey through guilt, confusion and fractured dreams in Simao's shadow. When he finally awakens three years later - his innocence preserved like a time capsule - his friends confront bittersweet truths: their struggles to outgrow teenage skins now mirror the very fractures that once bound them.
