A thrilling action-comedy in which the strongest housewife who once defeated terrorists on an airplane awakens once again and takes on a new hijacking incident on a luxury cruise ship. Uhm Jung-hwa reprises her role as Mi-yeon, a loving, ordinary housewife who is also a highly skilled former special operative.

Mi-yeon, along with her husband Seok-hwan (Park Sung-woong) and daughter, embarks on a long-awaited elegant cruise. However, the ultra-luxurious cruise ship they are on is seized by a mysterious terrorist organization led by a ruthless mastermind (Choi Soo-young). Trapped in the middle of the open sea with no escape, Mi-yeon finds herself in peril and once again unleashes her suppressed, overwhelming fighting instincts to save the lives of her family and the other passengers.

Uhm Jung-hwa powerfully and comically portrays the contrast between the approachable mother in everyday life and the former spy who ruthlessly takes down enemies with sharp, merciless action, even more so than in her previous role. The dynamic naval battles, which make full use of the vast ship's interior and deck, and skillfully utilize the surrounding props, are also a highlight. Her overwhelming presence and humor bring an unparalleled sense of exhilaration to this larger-scale film.
