Math is unyielding.
No matter how desperate the circumstances, no matter how dire the situation, math won’t suddenly offer a more promising result.
Writer/director Joe Penna’s absorbing Stowaway — a Netflix original — is Tom Godwin’s “Cold Equations” writ large (and a nod to that 1954 sci-fi classic would have been nice). Penna and co-scripter Ryan Morrison have “opened up” Godwin’s short story quite effectively, expanding the character roster, modifying the setting and circumstances.
But the core imperative remains the same: You simply can’t argue with math.
The story, set in a future when Mars has been colonized, begins as a Kingfisher rocket blasts off from Earth, under the command of Marina Barnett (Toni Colette). She’s joined by medical researcher Zoe Levenson (Anna Kendrick) and biologist/botanist David Kim (Daniel Dae Kim), accomplished academics chosen from thousands of applicants who submitted proposals for Mars-based research.
They dock with the Hyperion MTS-42, a modular space station. The spent rocket is transformed into a spinning counterweight at the end of a 500-meter-long tether; this supplies artificial gravity for the months-long journey to Mars. (Very cool concept, I might add.)
Shortly after this lengthy trip begins, during routine safety checks, Marina discovers an unconscious man in an overhead compartment that contains the Carbon Dioxide Removal Assembly (CDRA). When the body drops to the floor, his weight breaks Marina’s forearm; his safety harness, wrapped around a pipe attached to the CDRA, also inflicts damage.
Once he regains consciousness, the newcomer proves to be Michael Adams (Shamier Anderson), a ground crew engineer who blacked out after injuring himself during final pre-flight checks.
(I know, I know. The notion that there wouldn’t be some sort of personnel role call prior to take-off, is rather difficult to swallow. We gotta just go with it.)
(Technically, Michael also isn’t a stowaway, since he’s present accidentally, rather than intentionally. But that really is picking nits.)
Michael initially is horrified by the implications of his plight; the MTS-42 already has traveled past the point of no return, which means he’s looking at a two-year leave from Earth. This is agonizing — and Anderson plays this quite well — because he’s the sole support for his younger sister Ava, back on Earth. Happily, Hyperion officials — reached by radio — rise to the occasion, and promise to house and support her.
At which point, Michael calmly accepts the situation, and promises to “carry his weight” to whatever degree the others can use him.
Ah, but there’s the rub.
