It's high drama at LA Ink as tensions between Kat Von D and Corey Miller finally reach a head. How will Kat cope without her rock? There is never a dull moment as Kat's prankster roommate Rooftop joins the gang, and with a whole host of new ventures up her sleeve, Kat has certainly got her hands full. But with Michael, Dan and the rest of the High Voltage crew, the shop continues to thrive as more satisfied customers, including Lord of the Rings star Dominic Monaghan, leave with a smile on their face, ready to show off their new ink. Meanwhile across town, rival tattoo shop American Electric, with its crew of familiar faces, has dramas of its own as new girl Ruthless seems intent on stirring up trouble.
