As Archer, Tucker, and T'Pol celebrate T'Pol's first anniversary as a member of the crew, T'Pol drops a bombshell: Vulcan first contact with Humans wasn't with Zephram Cochrane in Montana, but in the 1950s in a mining town in Pennsylvania.
Soon after Sputnik 1 was sent into orbit, a four-man Vulcan ship (including T'Pol's great-great grandmother, T'Mir) was studying the event when its impulse manifold malfunctioned forcing a crash landing. With the captain dead, T'Mir was in charge. After running out of food, Mestral opts to make first contact -- which Tucker reduces to, "Two Vulcans stroll into a bar, hustle a few games of pool, and walk out with an arm-load of TV dinners."
With no rescue in sight, the three surviving Vulcans assimilate as well as possible. T'Mir takes odd jobs, Stron becomes a handyman, and Mestral works in the mine. Mestral bonds with the humans, and romanticizes their culture -- and is on the receiving end of some romantic overtures himself. T'Mir, too, finds that maybe Humans aren't all bad when she bonds with a boy wanting to go to college (which T'Mir helps finance by selling her "invention"... Velcro).
A mine accident causes Mestral and T'Mir to team up to help save the trapped miners using advanced technology, but without being discovered. After that success, more good news--a rescue is on the way for the Vulcans as well. Mestral wants to stay, and T'Mir allows it.
Reed and Archer enjoyed the story. T'Pol is enigmatic when asked about its veracity. Later, in her quarters, she pulls out of her personal effects a well-kept 1950s handbag.
