Imani (2020)

2030. In response to climate migration, the government has set up a program to receive refugees. Imani, originally from the sunken island of Sao Tome and who is stateless and traumatized, is recognized as a climate refugee in Seine-Saint-Denis. She joins the Green Fugees program, which will enable her to obtain French nationality provided she overcomes her trauma: will she manage to swim again?

Unfortunately the movie Imani is not yet available on HBO Max.
