Cold Front ( episode ) Archer is confronted by a member of his crew who claims to be from nine hundred years in the future – and is there to capture a Suliban operative who has boarded " Enterprise " . Summary . Teaser . In a temporal chamber , the Humanoid Figure reminds Silik , bound to a medical bed , there are consequences to his failure to destabilize the Klingon Empire . He then orders a Suliban doctor to proceed with an operation to remove Silik ' s enhanced vision . Act One . On the , Captain Jonathan Archer has a meal served by crewman , explaining that they are on the way to a stellar nursery where a few ships are stopped . There , the ship encounters a transport ship whose captain , Fraddock , explains with some annoyance that there are Borothan pilgrim s aboard , who have come to see the Great Plume of Agosoria , a phenomenon their religion associates with the beginning of the universe . Archer invites him , his crew and the pilgrims aboard to show them " Enterprise " . Fraddock declines , but says he ' ll pass on the message . Commander Tucker and Sub - commander T ' Pol join Archer to greet about a dozen guests . One of them happily greets Archer and the group have brought gifts for the crew . Archer offers a meal for them , and they accept even though they usually fast . Later in the mess hall , the alien group talks about their belief in the Plume . Doctor Phlox points out the cycle of re - birth is not unlike in Hinduism . Archer is asked if he follows a faith , but he prefers to keep an open mind . Meanwhile , on the bridge , Malcolm Reed sees Hoshi Sato return from meeting the guests and asks what they ' re like . He ' s in disagreement with a full ship ' s tour , preferring to keep tactical areas off - limits . In engineering , the tour continues , with Tucker giving a basic explanation until one of the aliens reveals he ' s actually a warp field theorist . Another one asks a detailed question , and so Tucker goes to show him the answer , however , another alien parts from the group and discretely tampers with the engine while he does so . As a few of the aliens are learning about the sickbay imaging systems , " Enterprise " is hit by a plasma storm . It is not deemed serious , but soon an antimatter cascade occurs , nearly destroying " Enterprise " . Engineering panels erupt closer to the engine until it unexpectedly stops . Tucker reports he was not responsible for the lucky outcome . Act Two . After the aliens leave ( taking Phlox along with them to visit their ship ) , Tucker found the tampered junction and believes one of the aliens did it . He calls Archer to engineering to explain . Archer then gets Fraddock to question the alien group , but he soon reports that none of them admit to it . As Archer leaves his ready room , Daniels catches him and wants to talk to him . Archer explains he ' s busy , but then he begins to explain he thinks one of the aliens is a Suliban . Now Archer stops , and Daniels brings him to his quarters to explain . Daniels reveals he is not in Starfleet , and from the future , with an organization that prevents factions tampering with the timeline . Using a device that projects something he calls a Temporal Observatory , he then talks about the events of a Temporal Cold War , and claims that the 22nd century is seen as an important front in the war . Archer is skeptical at first , but is convinced when Daniels reveals facts that would be impossible to know otherwise . He reveals that there is a Suliban named Silik aboard " Enterprise " , who saved the ship , and must be captured by Daniels . Further , he needs help from Archer to tie in his devices with " Enterprise " s in order to track Silik . Captain Archer offers Daniels his full cooperation , though he will need to inform a few people . He explains the situation to T ' Pol and Tucker . They express skepticism , as they can explain away the odd circumstances . Despite this , he orders them to cooperate with Daniels . He then learns that some of the aliens want to return to the ship to view the Plume . Act Three . Archer meets up with the aliens , now preparing to view the Plume . Phlox , back from his visit , tells the captain how interesting his time was . Archer is preoccupied , though , and asks Phlox about the alien ' s behavior . Phlox didn ' t see anything out of the ordinary , so he leaves . Meanwhile , Daniels works with Tucker and T ' Pol . His technology is amazing , with holographic displays and a phase device that allows him to walk through walls . Daniels works quickly , but does answer the occasional question about himself and Earth . Later , Archer is feeding Porthos , who barks excessively at nothing seemingly . Then , Silik appears , making contact with the captain to find out who is searching for him : he has detected tachyon radiation that would not normally be on the ship , as there are no devices on board that emit tachyon s . Archer feigns ignorance about Daniels initially , to which Silik presents relativist arguments about Daniels just being in another faction and not being who he seems to be . He also suggests that the antimatter cascade was not accidental , and reminds the Captain that he ( Silik ) saved the ship and every life on it . T ' Pol then makes an unfortunate communication , revealing that it is Daniels who is seeking him . Silik then stun s the captain and leaves . In Engineering , Daniels brings his sensors online and detects Suliban life signs . Tucker then notices a movement on the catwalk , and orders everyone except Daniels to evacuate Engineering . Silik appears , and twice shoots Daniels , who seems to explode , but his body parts disappear . Outside , Tucker calls the captain but he doesn ' t respond , so the two leave and call Phlox to get to Archer ' s quarters . Act Four . Phlox revives Archer , and immediately calls Reed to lock down hatches and find the intruder . Fraddock says no one has returned to his ship , so Silik must be still on board . Archer also finds that Silik has stolen Daniels ' Temporal Observatory device from his quarters . After Tucker works out how Daniels ' sensor system works , he pinpoints Silik ' s location . Archer goes after him with the phase device , catching him in a small room . After a brief struggle there and in the shuttlebay , during which turbulence from the Plume disrupts both men , Archer destroys the Temporal Observatory device with a phase - pistol . Silik tells him " " You may have endangered your future , Jon , " " leaving the captain with a final puzzle . Due to Silik ' s ability to appear invisible , Archer continues to lose him . Silik escapes by flinging himself out of the launch bay , toward a . On the bridge , T ' Pol informs Archer the ship went to warp , but Archer decides to stay put . Archer orders Reed to seal off Daniel ' s quarters and re - assign Daniel ' s roommate , stating that there may be more technology inside . Daniels ' quarters are thereafter locked .
