That identity, moreover, is fragmented into multiple versions that Lina has inhabited throughout her life, and the film articulates this through the different names she bears: Cata, the young woman of modest origins; Lina, the intimate, everyday self; Catalina, the public and professional figure. Each name operates as a social mask and as a role that demands the expulsion of certain parts of the self. The film is not about mental illness, but about the impossibility of sustaining contradictory identities without tearing oneself apart. To be Catalina means sacrificing Cata; to be a mother means relegating Lina; to be successful requires hiding vulnerabilities that nevertheless persist. From this perspective, the jump into the river is a liminal gesture rather than a conventional suicide attempt: a symbolic death, a rite of passage in which identities cease to coexist and the protagonist sheds the version of herself she can no longer bear. The fall, that instant suspended between floating and sinking, shows that the self can no longer withstand the pressure accumulated between external expectations and repressed subjectivity. There is no need to explain the reasons for the jump because those reasons belong to the realm of rationality, while the act itself emerges from emotional urgency: the cause often arrives later and, at the moment of rupture, the body decides before thought.
From that point on, a process of identity decomposition begins, in which the protagonist confronts the impossibility of returning to her former life. The routines that once sustained her existence become unbearable, and her roles as mother, wife, and public figure enter into crisis, not because she ceases to love her daughter or loses interest in her work, but because she has lost the stability that once allowed her to inhabit those identities. This process is portrayed through minimal gestures: a visceral rejection of water, silence among her loved ones, an inability to respond emotionally. Everything becomes foreign, even the home, which ceases to be a refuge and becomes a threat. Within this logic of fracture arises the lighthouse sequence, one of the film’s most revealing moments. The protagonist climbs with her daughter to an improbable space atop the building where they live, and what might seem like a slip into the fantastic is in fact an epiphany: for the first time since the jump, Lina observes life without fear. The rotating light of the lighthouse washes over the city, illuminating fragments of other people’s existence, revealing her assistant walking, neighbors in their routines, strangers immersed in their own becoming. This expanded gaze is not voyeurism but a reconnection with human community, a momentary suspension of mental confinement, the confirmation that she had not lost the capacity for connection, only that she had been trapped in the opacity of fear.
In that sweep of the lighthouse beam, Lina does not flee; she reinserts herself into a world that is beginning to regain meaning. The light reminds her that life continues beyond fear and that even in crisis there are moments of perspective capable of breaking suffocation. The lighthouse functions as a sign of emotional clarity: it neither heals nor explains, but it offers the sensation that there exists a path back toward recovering a place in the world. The dialogue between water and light structures the film’s symbolism: if water threatens to dissolve, light proposes a moment of recomposition. These are not simply danger and salvation in opposition, but a tension between collapse and rebirth that reinforces the film’s central proposal: inner life is not linear, nor explainable through single causes, and it does not always answer to medical or narrative logic. Toward the end, the film rejects any univocal answers. It offers neither moral lesson nor definitive resolution because emotional recovery does not operate through closure, but through a coexistence with one’s own opacity. Las corrientes understands that there are crises that cannot be told but must be lived, identities that cannot be explained but overflow, fears that cannot be translated but are felt. Mumenthaler offers no solutions because she knows there is not just one: she films the zone where language collapses and where pain can only be perceived through textures, images, sounds, and silences. In doing so, she proposes a radical defense of human mystery. Her film’s beauty lies in accepting that there are regions of the mind that can only be filmed, never explained. It invites us not to understand Lina from the outside, but to accompany her—not to diagnose her, but to listen to the vibration of her fear.
