Billie, Mary Alice, Helen, and Natalie board what they think is a celebratory retirement cruise after four decades working as assassins for the Museum, an elite international organization. At sixty, the women have been told their old-school methods no longer fit the high-tech world of modern espionage. But when killers target them aboard ship, they realize the all-expenses-paid vacation is actually a termination order from the Board, the Museum's leadership. The four friends must turn their skills against their former employers to survive. They face younger operatives who dismiss them as obsolete while drawing on decades of lethal experience and unbreakable bonds of friendship. The women discover that being underestimated because of their age becomes their greatest advantage in a fight for their lives.
