Leonard comes home to find an upset Sheldon talking to a police officer in the living room. Sheldon goes on and on about how they stole everything. We learn that Sheldon's World of Warcraft account has been hacked and the character that he has spent years working on has been cleaned out. Essentially, identity theft of his online persona. Penny drops by to console Sheldon but runs into Priya and awkwardly leave. Priya, bored watching the guys play the game, decides to leave as well.
Hanging out later, the girls decide they no longer like Priya.
Wolowitz manages to find out who took Sheldon's stuff, and even has the guy's address down in San Diego. They make bold plans to go on a real-life adventure and travel the thief's house that evening. Leonard is worried about blowing off Priya two nights in a row, but is sure she'll understand.
After many delays in getting there, the guys are confronted by a huge nerdy teenager and get scared. The confrontation is a complete failure. On the way back home, Leonard's car breaks down and they call Penny to pick them up. When she finds out that they never got Sheldon's stuff back, she turns the car around, insisting she show them how they finish things in Nebraska. When the guy answers the door, Penny says "Give my friend his stuff back," knees him, takes him down and the guy agrees to give everything back. Sheldon (who did nothing) : "WE DID IT!"
