In the idyllic neighborhood of Zilker Park, Austin, three mothers—Whitney, Annette, and Liza—have nurtured a strong bond as they raised their sons in what seems to be a haven of safety. Bound by a fierce sense of protection and the confidence that their friendship is as secure as the community they call home, the trio of women believe in their power to shield their children from the world's perils. However, one summer's night alters everything. The boys, adolescent lifeguards, pedal back from a nocturnal swim, their shared secret poised to fracture the perfect facade the mothers have constructed. As the mothers' perspectives weave together with online neighborhood chatter, clandestine texts, and revealing police reports, "The Lifeguards" becomes an entangled narrative of devotion and deception. A summer that bids farewell to innocence is rendered through betrayals, resilient love, and the burden of secrets kept to guard those closest to us—a poignant exploration of motherhood, friendship, and the loyalty that binds and sometimes breaks us.
