Torchwood is a super-secret british agency that handles all alien contact. Their leader is the bisexual Capt. Jack. Who cannot die. I mean he dies often, but he always comes back. It's his curse. Capt. Jack leads a crew who investigate alien visits and kill bad aliens (almost all of them are bad and most sleep with us too). All of the crew has secrets, Jack is sleeping with his assistant, they do kinky things together. Anyway, the world's gone to pot at the start of season 2, disease has infected earth from all the time jumping. So it's torchwood to the rescue -- with plenty of sex, gay and straight and otherwise.
There's also a lot of crossover between Torchwood and Dr. Who.
And yah for all the other Torchwood fans out there. I also love Dr. Who. But I didn't want to seem like too much of a geek, lol.
