Colonel Hal Gascoigne finds himself alone aboard the orbital platform SV‑1, a sleek but eerie satellite orbiting Earth. When a phantom sergeant appears with a cryptic bomb order, the empty vessel’s alarms, empty corridors, and garbled teletype messages push him toward a terrifying decision. As the ship drifts in weightless silence, Gascoigne must decipher whether the command is a genuine military directive or a trap set by a mind gone mad.
The story unfolds in a claustrophobic, high‑tech setting where reality blurs with paranoia, and each click of the control panel could trigger catastrophe. Through Gascoigne’s internal struggle and the thin line of communication with a shadowy civilian intelligence group, listeners are drawn into a tense, psychological cat‑and‑mouse game. The narrative balances cold, procedural detail with an unsettling sense of isolation, making the first act a gripping puzzle of loyalty, sanity, and the terrifying power of a single command.
