Park Shin Hye, the actress who portrays the poor and ordinary girl Cha Eun Sang in the new drama "The Heirs", shows off her dance skills during one of the obstacles for this week's "Running Man".

The challenge was to find out who the true heir was through a series of obstacles and games where the cast of "Running Man" and "The Heirs" face off.

Joining her in this episode are her "The Heirs" co-stars Kim Woo Bin and Choi Jin Hyuk, as seen in the stills revealed by the "Running Man" staff. The two male members participate in the wrestling mission.

It is a race between the Yellow Team, which is composed of Haha, Song Ji Hyo, Lee Kwang Soo, Kim Jong Kook and Ji Suk Jin, and the Blue Team, which is composed of "The Heirs" cast Park Shin Hye, Choi Jin Hyuk and Kim Woo Bin, and Gary and Yoo Jae Suk.

They will be invading the "Cultwo Show" as part of their mission to show off their special talents on air. This is when Park Shin Hye wows the cast with her dancing skills that could be compared to the skills of girl group members.

It is definitely an episode to anticipate, so watch "The Heirs" cast on "Running Man" this October 6 2013 at 6:10 PM (KST).
