Friendship. It's one of the things in life that really matters and makes it worth living but, oh man, it ain't easy. Teenage assassins Mahiro and Chisato have been through a lot together, and they have each other's backs like true friends should. As the third Baby Assassins movie begins, they've earned a well-deserved holiday in Miyazaki, Japan, when The Agency calls them in on a local job, taking out an embezzler, that should be easy-peasy. No such luck. The gig has been double-booked by an unpredictably vicious freelancer, who isn't going to make it easy for our killer teen duo. Now forced to work with “adult” Agency supervision, Mahiro and Chisato will find their friendship (and killing skills) tested in unexpected ways, meaning the vacation is over—and the big two-oh is right around the corner for the girls. With a body count, of course. A big one.
