In the year 2032, Vicente, an eight-year-old Caribbean boy, has been displaced by global warming and fends for himself as an environmental refugee in a hostile Northern metropolis. Orphaned and without connection to family or friends, Vicente now lives in a children?s shelter on the fringes of the city, and struggles with anxiety, rage, and disturbing memories of the tragedy he fled. On a hot summer day, Vicente sits outside the shelter and sees a mysterious man smashing large chunks of ice against the pavement. Thus begins an unexpected friendship between Vicente and Siku, the ice carver: two people from different worlds who have both experienced tremendous loss. Through their bond, Siku ultimately helps Vicente confront his past and understand the value of memory.
