It's a family drama with a transgender subplot set in 1970 in Rome, Italy. It follows a summer in the life of a dysfunctional family.
Clara (Penélope Cruz) is the mother of three children. She is devoted to her children but has a rocky relationship with her philandering and abusive husband, Felice (Vincenzo Amato). Their oldest child, Adriana/Adri/Andrew (Luana Giuliani), is 12 years old, born as a girl but identifies as a boy. Gino (Patrizio Francioni) is a younger brother, and Diana (Maria Chiara Goretti) is perhaps a six-year-old girl.
Adri develops a summer friendship with a Romany girl named Sara (Penélope Nieto Conti), during which they identifies as Andrew. Their parents and extended family resist Adri's identification, though Clara is sympathetic. Eventually, the family encounters two crises, and Adri tries to escape through fantasy. "L'immensità" ends inconclusively.
The director came out as transgender with the release of this film. "L'immensità" tends to wander a bit but reflects a family in crisis very well. Cruz is probably too attractive for her role and tends to overshadow Luana Giuliani, who deserves great credit for a demanding and complex role.
