The sun‑bleached sands of Malibu hide a restless undercurrent, where carefree beach culture meets a shiver of unease. The ocean’s rhythm is punctuated by the distant hum of surfboards and the occasional splash of a wave, yet an unseen tension ripples through the salty air. In this seaside playground, the ordinary and the uncanny sit side by side, setting the stage for a thriller that feels both sun‑soaked and shadowed.

At the heart of the story is Otto Lindsay, a respected oceanographer whose work on marine life has earned him both acclaim and curiosity. His son Richard returns home with a taste for living in the moment, preferring parties and romance over his father’s disciplined research. Vicky, Richard’s stepmother, drifts through the household with a restless charm, while Mark—a scarred sculptor and longtime friend—offers a grounded, if weathered, perspective on life’s twists. Jane, Richard’s girlfriend, adds a touch of warmth and optimism, balancing the group’s dynamics as they navigate their intertwined relationships.

The film opens with a startling murder on the beach, an event that upends the tranquil rhythm of the coast. Otto is drawn into the investigation, proposing a scientific explanation that a mutated marine creature could be responsible. Meanwhile, Richard leans toward a more human threat, suspecting a vengeful madman may be targeting him and his friends. Their conflicting theories create a palpable clash of rationality and intuition, pulling the characters—and the audience—into a web of speculation.

As the mystery deepens, the sun‑drenched setting becomes a character in its own right, its beauty masking a growing sense of danger. The story balances breezy summer vibes with an undercurrent of dread, inviting viewers to wonder what lurks beneath the waves and within the minds of those desperate to uncover the truth.
