The Plan — 100 Milligrams

Written by Rian Johnson, this gripping contemporary duologue from the mystery thriller Knives Out revolves around a sudden, high-stakes medical crisis. When a dedicated nurse accidentally administers a fatal overdose of medication, panic sets in as she scrambles to locate an emergency antidote. Facing an irreversible countdown to his own demise, her elderly patient—a seasoned mystery novelist—remains astonishingly calm, treating the situation like an elaborate puzzle as he devises a plan to protect her and her family.

Marta is deeply vulnerable and consumed by rising terror, shifting rapidly from clinical professionalism to sheer helplessness as she realizes the antidote is missing. Her objective is immediate survival and moral accountability, making her physical urgency intense and raw. Harlan functions as a steadfast mentor and compelling character role, meeting impending death with an eerie, analytical detachment. Rather than yielding to fear, he channels his instincts as an author, coolly assessing timelines and consequences to orchestrate a safeguard for his caregiver.

This scene provides an extraordinary contrast in energy, placing frenetic desperation directly opposite calculated composure. The explicit ten-minute ticking clock establishes instant dramatic stakes that demand immediate emotional commitment from both performers. Casting directors can easily evaluate an actor's ability to handle rapid dialogue, authentic physical panic, active listening, and grounded vulnerability without losing control of the text.

Clocking in at roughly four minutes, this piece is well suited for self-tapes, agent showcases, and general partner practice. It is particularly effective for actors fitting intense, vulnerable, mentor, or seasoned character actor casting profiles who want to demonstrate their command of modern suspense.

Ground Marta's frantic pacing in specific physical actions rather than generalized hysteria, allowing her terror to emerge from failed problem-solving. For Harlan, resist the temptation to play the physical symptoms too early; his strength comes from an unsettling mental clarity while facing mortality. Ensure that both actors actively bounce off one another's opposing tempos, as the tension thrives entirely on the friction between his stillness and her kinetic despair.
