This heartwarming duo describes the many layers (and many years) of a sister sister relationship between Rachel and Laina. From playtime and “rap” concerts in their youth, to life-saving sacrifices, Rachel and Laina consistently show up for each other despite their differences. Laina is a nerdy reserved woman who ends up marrying her high school sweetheart and having a baby. Rachel is an independent wild child who turns into the “fun aunt.” But when Laina is diagnosed with kidney failure, Rachel knows she’ll do anything to save her sister’s life.
