"Hello America!" Jun-ha shouts as Infinite Challenge members are outside the airport. The members greet as the camera starts filming them. Jae-suk said, "Now we're here in America for the newest episode, Around the World Challenge!"

Kwanghee cheers out loud and Jae-suk continues, "Today, we will have a special guest to join the Around the World Challenge."

"Yahoo!!" Myung-soo claps and Haha asked, "Is it a female actress or singer?"

"Let us presenting..." Then, a song is played. It is a song sung by a Kpop boy group. Kwanghee surprisingly knows the song and he is flustered. ZE:A members come out, shocking everyone. Kwanghee quickly joins the members and they do their group introduction. They all clap and Kwanghee hugs Siwan tightly. He said, "I miss you so much."

"Oh my..." Siwan mumbled. Haha said, "This is the main event."

"So, what are we going to do with the challenge?" Kevin asked. Jae-suk takes out a card and reads, "To complete Around the World Challenge, you must pass five challenges. Create a group of seven and go to New York City."

Heechul pushes Kwanghee and said, "You are in Infinite Challenge team."

"I want to be with Siwan~." Kwanghee pouts and Siwan walks to Kwanghee. He said, 'I'll be with you."

"No fair!" Hyunsik exclaimed.

"Let's go!" Lee Ho sai
