|“||"But I got a mantis in my pantis."||”|
- Main article: The Deadly Mantis (film)
In the South Seas, a volcano explodes, eventually causing North Pole icebergs to shift. Below the melting polar ice caps, a 200-foot-long praying mantis, trapped in the ice for millions of years, begins to stir. Soon after, the military personnel at Red Eagle One, a military station in northern Canada that monitors information gathered from the Distant Early Warning Line, realize that the men at one of their outposts are not responding to calls. Commanding officer Col. Joe Parkman flies there to investigate, and finds the post destroyed, its men disappeared and giant slashes left in the snow outside.
When a blip on the outpost's radar screen is soon sighted, Joe sends his pilots out, and one is attacked. Joe searches the wreckage, and this time, in addition to the huge slashes, finds a five-foot-long pointed object in the snow. He takes it to General Mark Ford at the Continental Air Defense Command in Colorado Springs, Colorado. Ford gathers top scientists, including Professor Anton Gunther, to examine the object, but after they fail to identify it, Gunther recommends calling in Dr. Nedrick Jackson, a paleontologist at the Museum of Natural History.
When Ned receives the call from Ford, he is helping museum magazine editor Marge Blaine plan her next issue, and later dodges her questions as she begs him for a big scoop. Later, after examining the object, Ned recognizes it as a torn-off spur from an insect's leg, and soon guesses, from evidence that the creature ate human flesh, that it must be a gigantic praying mantis. Meanwhile, in the Arctic, the people of an Eskimo village spot the mantis in the sky, and although they hurry to their boats to escape, it swoops down and kills several men.
Ned is sent to Red Eagle One to investigate further, and upon leaving, discovers that Marge has finagled permission to accompany him as his photographer. They reach the base, where all the men, including Joe, are smitten by Marge's beauty. That night, Marge and Joe join Ned in his office and discuss the creature, not realizing that it is drawing close to the office window. Marge suddenly catches sight of it and screams, and the bug attacks the building. Although the full unit opens fire on the mantis with automatic rifles and a flame-thrower, it is unscathed and moves away only after planes encircle it.
Hours later, the base remains on red alert, but they finally hear that the bug has attacked a boat off the Canadian coast, which means, Ned calculates, that it is flying at a speed of 200 miles an hour. Ford calls a press conference to announce the bug's existence, and asks the Ground Observer Corps to track its whereabouts. Over the next few days, Ned, Marge and Joe tirelessly track the bug's progress, with the help of military and civilian observers. Late one night, Joe drives Marge home, stopping briefly to ask for, and receive, a kiss. They are distracted by a report of a nearby train wreck, and although they assume it to be an ordinary accident, soon after, a woman leaving a bus sees the mantis, and all emergency personnel are put on alert. The mantis is then sighted in Washington, D.C., atop the Washington Monument.
Joe is one of the pilots who bravely attempt to drive the bug toward the sea, but a dense fog throws him off course, and he flies directly into the mantis. As the wounded mantis drops to the ground and crawls into the Manhattan Tunnel, Joe safely parachutes to the ground. Ford heads a team that seals off the tunnel, filling it with smoke to provide cover for Joe and his special unit of men, who enter the tunnel armed with rifles and three chemical bombs. They creep past wrecked cars until suddenly the bug appears in the fog only a few yards ahead of them. They shoot at it, but it lumbers on, forcing them backward. The mantis seems immune to the ammunition and the first chemical bombs until, only feet from the tunnel entrance, Joe throws a bomb in its face, and it collapses, dead. Later, Ford, Ned, Joe and Marge enter the tunnel to examine the bug. Marge photographs its face while the men walk around its side, but Joe suddenly sees the mantis' arm move, and runs to protect Marge. Although Ned explains that the bug's movement was merely an autonomic reflex, Joe takes the opportunity to pull Marge into an embrace. 
- Some of the Arctic scenes in The Deadly Mantis were culled from the 1933 drama SOS Iceberg and a handful of Air Force training films. 
- Alix Talton was reunited with William Hopper the following year 1958 on the Perry Mason TV series episode "The Case of the Long-Legged Models" in the role of Eva Elliot.
- During the movie, the Air Force sends out a message to members of the Ground Observer Corps asking for help in spotting the mantis. This was a real group that existed in two incarnations. The first was during World War Two, and was comprised of civilians who received basic training in spotting and identifying aircraft. It ended in 1944. The GOC was revived in 1950 as part of the Cold War, and was discontinued in 1958 (primarily due to advances in RADAR).
- Prologue It's business casual day on the Satellite of Love. Tom makes up useless dress codes and implies that Mike is breaking them. Mike counters that they're not a business so the entire exercise is foolish.
- Segment 1 In Deep Ape Bobo and Dr. Peanut are helping theirs friends from the mutant H-Bomb cult (Beth "Beez" McKeever, Bill Corbett and Paul Chaplin) reactivate the nuclear warhead that they worship. Though the apes are struggling at first a helpful suggestion from Mike sets them on the right track and they repair the bomb quickly. Pearl sees this and tells Bobo to start Mike's movie while she flees. Mike begs the nanites to repair The Satellite of Love and only finds one on duty that day. The lone nanite refuses to do it without a work order. After some arguing Mike's work order is found. The nanite repairs the SOL so rapidly Mike doesn't notice the control panel that instantly sprung up on the table in front of him. He steers the satellite to a safe distance seconds before the bomb detonates.
- Segment 2 Tom puts on a minister's vestments and performs a eulogy for Pearl and the other inhabitants of the planet Earth. Their solemn service is interrupted when Pearl turns out to be alive. She's in her van, The Widowmaker, with a revolver trying to shoot the Satellite of Love. Pearl discovers that Bobo has stowed away on her space van. She hands him a gun but Bobo only manages to shoot himself in the foot twice. Gypsy takes control of the ship and evades Pearl by hiding behind an asteroid.
- Segment 3 Mike dozes off at the wheel of the Satellite of Love. He and the bots (with the exception of Crow, who just mainly sleeps it off for most part of the segment) try to stay awake by listening to the space radio. All the channels they can pick up only play space country and western music, much to everyone's annoyance.
- Segment 4 Tom tries his hand at steering the satellite. He accidentally hits a space creature, much to his despair. Crow goes to check on the blue, blob-like creature (Patrick Brantseg) and brings it inside. The creature proceeds to eat Crow. After several failed rescue attempts Mike gets the creature to regurgitate Crow, though he comes out partially digested.
- Final Segment Crow serves Mike and Tom a mysterious meatloaf which turns out to be the creature that ate Crow in the last segment. Mike receives a letter from Dr. Peanut who was blasted back to the 22nd century somehow. Dr. Peanut is dating someone who may be Mike's future great granddaughter. Pearl calls to swear she will never give up her pursuit of Mike and the SOL.
