At school, Catherine (Laura Laura Linney) is a respected history teacher. At home, she becomes the backbone of her family, and her quiet life has gradually become a burden on Catherine. But the reason why she wants to change her life so badly is not that, but that she finds herself suffering from cancer. Catherine decided to keep it a secret and keep it a secret. Whether it is Catherine's idle brother Sean (John Benjamin Heike John Benjamin Hickey) or her never-growing husband Paul (Oliver Platt Oliver Platt), they are skeptical about Catherine's "ambition". Fortunately, Catherine's attending doctor Todd (Red Scott Reid Scott) has been firmly supporting and encouraging Catherine. Cancer is now, if there is tomorrow, will tomorrow really be better?
