A family on the verge of collapse deals with internal tensions as the mother, frustrated and focused on money, has filed for divorce against her weak and unassertive husband. Their daughter, burdened with household responsibilities, feels taken advantage of, while the youngest child, known for his sharp tongue, is caught in the chaos. As their relationships unravel, they are unexpectedly approached by the Galaxy Federation to defend Earth from extraterrestrial threats, offering them an opportunity to protect the planet and possibly mend their own fractured bonds.
