Yoo Joong Won (Lee Beom Soo) hands Kim Yeon Hwa their sister's contact information before he dies. Kim Yeon Hwa waits for her older sister on a bench at a deserted place after contacting her sister, Kim Sun Hwa to meet. The killer sisters are finally reunited when Kim Sun Hwa shows up at the location.

Kim Yeon Hwa says, "Where were you? You don't know how much I tried to find you" and hugs Kim Sun Hwa. Kim Sun Hwa replies, "I'm sorry for showing up so late" and begins to cry.

However, their tearful reunification is interrupted when an unidentified group of killers attack. Kim Sun Hwa and Kim Yeon Hwa both change completely and turn into cold-hearted killers themselves.

The killer sisters drew attention until the very end with their powerful alpha-female images.

Meanwhile, Yoo Joong Won is killed by Yoon Shi Hyuk (Lee Joon) and fails his attempt to detonate the nuclear bomb.

The drama ends with a tragic ending.
