A crack in time — Jack and Tosh come screeching around a corner and zooming down a side street in the Torchwood SUV. They come to a halt in front of an abandoned music hall. Tosh is on her cell, talking to her grandfather in Japanese — it's his 88^th birthday. Dressed up in a purple silk dress for his party later that night, Tosh accessorizes with her laptop because you can't check your email from a Kate Spade bag. She hangs up and stands in front of the door with Jack.

Torchwood received some anonymous calls about mysterious 1940s music drifting out of the boarded-up building, so Jack and Tosh let themselves in to investigate. Inside, the remains of long-ago parties litter the floor, fading flyers announcing WWII "Kiss the Boys Good-Bye" dances and bands still cling to the walls.

Suddenly, Jack and Tosh can hear big band music emanating from somewhere nearby. They follow the music to the upstairs dance floor. There's nothing there except some fixtures covered in plastic tarps and a very old chandelier. Jack admires the chandelier with appreciation. Gay men and their antiques – a match made in heaven.

Jack grabs Tosh and spins her around the dusty dance floor, imagining what it must've been like back during the war.

Jack: …Just dashing young soldiers and pretty young ladies… and as they danced, the girls would look into their partners eyes and smile softly and say…
Tosh: Jack! Mind my laptop!
Jack: [laughing] I was thinking more along the lines of, "And how long before you head off to war?" Heh, heh.

Antiques make Jack giddy.

Not finding anything upstairs, they head back down a large staircase to leave. That's it? No Torchwood alien detection sweeps or time-space rift monitor readings? They don't even look to see if there's an old codger squatting in the building who happens to be a Benny Goodman fan.

But then, the music starts up again and this time, audible voices can be heard as well. Jack and Tosh turn around and go back upstairs. The musty room they just left is now alive with people in period dress. "They look so real," Tosh says, amazed.

Jack tells her they are real. There was a "temporal shift" and it's 1941 all over again. He grins broadly, hoping to take one or two pristine antiques with him back to 2007.

Tosh snaps Jack back to reality and tells them they have to get out of there — this is not their time. As they leave, the hall manager, a creepy old coot with dead doll eyes named Bilis Manger, holds the door open for them and bids them good evening

Outside, day has turned to night and the SUV is gone because gas-guzzling, soccer team-car-pooling vehicles have not been invented yet. There goes your ride home.

Act natural — Back at the hub in the present day, Ianto is monitoring Tosh's computer and sees her rift monitoring program sending an alert message. Owen wakes up from his cat nap, checks his morning breath, and gets the update from Ianto.

Ianto tries to call Tosh's cell at the same time Tosh is trying to call the hub, but they're 66 years apart and for once, no one can blame T-Mobile.

Back at the dance hall, Jack is being awfully cavalier about getting back — "flotsam and jetsam" fall through the rift all the time — they'll get back somehow. He tells Tosh to relax and enjoy the history before them. Not as big a fan of the 40s as Jack is, Tosh worries they won't be able to go home and she'll be stuck in an era with no Wi-Fi.

Tosh tells Jack she has a life back in 2007. A life of frozen, single-serving dinners and an inexplicable, yet relentless, pining for Owen, but a life nonetheless. Jack takes off his bluetooth and tells Tosh they have to blend in. Act Caucasian.

Rift Alert — At Torchwood, Owen is messing around with Tosh's rift program: a series of complex, gibberish math equations. Hey. I was told there would be no math.
