When N'Kalla - Skrull and adopted daughter of Ben Grimm and Alicia Masters - sees her brother Jo-Venn get in trouble at school and be sent to the principal's office, she does the sisterly thing... which is, of course, to shape-shift into a double of their father Ben to get him out of it! And when her cousin Valeria gets in trouble, "Reed Richards" arrives to get her off the hook, and soon "Sue Storm" is excusing Franklin for his misbehavior too... But when she gets caught in her deceptions and grounded, things go from bad to worse when a super villain attacks and the Fantastic Four are nowhere to be seen! Questions of strength, super-powers, identity and love all come to a head as lives hang in the balance!
