“So, we got yanked off course by a giant vacuum cleaner?”

It is the fifth day of the Enterprise’s work roster. There are only minutes on the chronometer until the end of alpha shift and the weekend will officially begin. A course has been plotted to Starbase 7 for upgrades to the ship’s Bussard Collectors. Uhura is excited because Ensign Rankin will be playing piano in the Port Galley. Meanwhile, Dr. Philip Boyce (a character who hasn’t been seen in Star Trek since “The Cage”) is scheduled to arrive in sickbay soon. He was once the interim CMO on the Enterprise, he transferred back after apparently not getting along with anyone on the Sunita. Dr. M’Benga is bringing him aboard the Enterprise as a reliable replacement in the event that M’Benga leaves, which concerns Nurse Chapel. M’Benga and Chapel have an argument over her commitment to the ship.
But suddenly a strange “slipstream wormhole” filled with a high concentrate of neutrinos sucks the Enterprise inside and, moving at warp speed, it causes a malfunction to the ship’s warp engines. The whole ship’s systems get fried and electrocuted. Pike manages to activate the deflector shields but he is knocked to the floor unconscious while engineering gets flooded with dangerous lethal levels of neutrino radiation, meanwhile Dr. M’Benga gets severely injured in sickbay by a desk that effectively severs him in half (but the pressure keeps him alive like Mel Gibson’s wife in M. Night Shyamalan’s Signs). With M’Benga out of commission, the curmudgeonly Dr. Boyce claims he is now CMO and instructs Chapel to abandon M’Benga in order to the save others, but Nurse Chapel refuses. Then the artificial gravity system starts malfunctioning. The whole ship is thrown into violent disarray, isolating the crew in various sections of the ship.
Scotty and Spock are sent on dangerous internal missions. Spock dons a space suit and climbs the hull of the ship to an outer pod in order to collect valuable data while Scotty is transported inside the ship to engineering using the last power available for a single transport, while Nurse Chapel explores using a hypothetical procedure on Dr. M’Benga (one he investigated for his sick daughter). Chapel proposes using the high levels of neutrinos in the wormhole to heal M’Benga (the neutrinos can apparently also serve as fuel for the ship).
Naturally, this whole far-fetched plan succeeds on every level: the ship manages to power its way out of the slipstream wormhole while all the wounded onboard survive thanks to some miraculous technobabble. The episode ends as Scotty shows his deep love for the Enterprise after trusting it to overcome the crisis, and Nurse Chapel decides to change her temporary employment status on the Enterprise to the more standard permanent status (even though Dr. M’Benga is considering leaving the Enterprise).
My Thoughts on “Off-Hour”
A wild catastrophe episode a la TNG’s “Disaster,” “Off-Hour” is a brutal, action-packed episode that sees key members of the crew put in severe mortal danger. Pike is electrocuted, Scotty risks his life in engineering, Spock suffers from radiation sickness, La’an rescues Spock outside the ship, Una’s leg is broken while she attempts to restore life support systems, Nurse Chapel’s finger snaps, and M’Benga is effectively severed in half before nearly freezing to death. But through the miracle of the wormhole neutrinos and plenty of nonsensical technobabble, the ship escapes from the clutches of the slipstream wormhole and all is put to right.
“Off-Hour” is a serviceable gripping action-adventure ensemble episode, a jarring tonal shift from the utterly clownish gimmicks that much of this season has been mired in, but it is easily one of the better episodes this season (somewhere on par with “The Griffin Incident”) but that’s not really saying much.
Star Trek Trivia:
- This episode has been often compared to the TNG episode “Disaster” and other television shows like 24 with its ticking clock chronometer.
- This episode reminds us that Nurse Chapel is on civilian exchange from the Stanford Epigenetic Project.
- Dr. Philip Boyce makes a brief appearance in this episode. It is the first time the character has appeared in Star Trek since the unaired pilot episode “The Cage.” In “Off-Hour,” he is played by Brian Markinson.
- Some of the background crewmen in this episode include: Lt. Rahda, Lt. Early, Ensign Rankin, and the Vulcan cadet A’Sha, who mentions she is a vegetarian like many Vulcans.
- In this episode, “Lt. Junior Grade Montgomery Scott” issues Starfleet Safety Protocol 429 which orders crew members to vacate certain corridors.
- Nurse Chapel uses Mylar blankets in sickbay to keep warm in negative 400-degree temperatures.
