The series explores the complex relationship between divorced parents Vicky and Stephen and their views on supporting their youngest child, Max. From an early age, Max has identified as a girl, but tried to suppress these feelings in an effort to gain his father's sympathy. When Max's feelings become increasingly distressing for the family, Stephen jumps at the chance to return to the family home, hoping to encourage male bonding with Max and prove himself to Vicky. The apparent differences of opinion between Stephen and Vicky initially thwart Max's social transition to Maxine, but his confidence grows and he becomes increasingly confident in doing what he has to do.
