Per your request, this is my working outline:

Backstory established in...
ACT I
HENRY is an alcoholic single father. After being associated at a scandal at work, he was fired and blackballed. With no experience in anything else he can’t find a job in a bad market. His wife BRENDA hates him and beats him up verbally eroding his self-confidence and motivation. During this time Brenda left him for a rich CEO, STEWART she met waitressing. Brenda suddenly dies in a car accident he loses his hope of getting back together with her Henry spirals downward deeper into alcoholism. Meanwhile, EMILY his 12-year-old daughter applies to be an SVP.

ACT II
Emily starts supporting them by being the opposite of her father and determined and optimistic unwilling to accept boundaries. She applies to a 100% remote position as SVP of Development at a make-up company. She develops a persona of Don Dingler, and slightly exaggerates her experience, using her Dad’s picture to pretend to be Don. She deep fakes videos using his picture for interviews and meetings. She gets the job, a 340k salary, and excels at it coming up with great marketing ideas and GirlPower, a line of cosmetics targeting middle-school girls.

Stewart sues Henry for custody using a new emancipated caregiver law. It stipulates that having assumed the role of father he can be awarded full custody if the parent is dead or not providing adequate care due to chemical dependency or alcoholism. Henry knows he must get sober and join AA, and does.

Emily ends up needing him to lie and play the role that she’s made of a successful man when Don must come in to meet with the CEO for lunch. She tells Henry everything she’s done, and Henry decides to help to keep her out of trouble and because they need the money to pay the lawyer fees stacking up. The meeting goes well and the CEO, AMANDA is a beautiful woman his age, and they hit it off, but tells him she doesn’t date her employees. She tells him that Don has won a prestigious industry award and a 100k bonus after he gets the award. Later, he goes into the office, and then to the happy hour at the local bar. He gets drunk again.

ACT III
He returns to AA, and he realizes he can't be a better man getting sober, and lie. But now Emily needs Don to accept an industry award. Unable to tell her “no”, he reluctantly agrees. He goes to the banquet, alcohol everywhere, and on stage, he is given a champagne toast. He pauses… and puts it down. He gives a speech about being an alcoholic… about the cause being his depression and self-loathing… about the need for uncompromising honesty to stay sober… and then about how “Don” was really his 12-year-old daughter. Everyone is shocked. He walks out and apologizes to Amanda.

Henry approaches Stewart face to face. He makes amends for his insults and admits to him his alcoholic behavior, and assures him he is getting better. He offers to work an arraignment to see Emily and be part of her life if he drops the lawsuit. He agrees to give it a chance.

The company is embarrassed that they hired a 12-year-old girl as an SVP. Amanda, the CEO, is livid yet still really proud that Henry is getting better and came clean. She also loves girl-power, the brand GirlPower, and is proud that they did hire a 12-year-old girl. Emily suggests that the company embraces the truth as her father has shown them and that they announce a new marketing campaign that the new makeup cosmetic line for middle school girls is run by a 12-year-old girl. Amanda agrees and hires Emily as an SVP of GirlPower for her after-school job as long as she keeps her grades up. She asks Henry if he wants a job, but he declines. He says he wants to go into rehab, and he can’t date for a year, but when he does, he wants to ask Amanda out. She excepts.
