Teen activism is on the march! Socially conscious young adults are speaking out. AN UNACCEPTABLE CHRISTMAS celebrates the courage it takes to stand up to authority. Call it a political It's a Wonderful Life for a new generation. 

Six-year-old MICHAEL has only one Christmas wish: that his military father—who is missing in action in a far-off war—will be found safe. He states his request in a heartfelt letter to Santa. Sadly, the boy's prayer for his dad's return will not be delivered. The Supreme Court has ruled that there is no Santa Claus, and lawmakers have banned all Santa-related activity.

Denying Michael that solace infuriates HOLLY, his normally reserved teenage sister. Though agreeing that Santa is imaginary, she is appalled that Washington would punish people for what they choose to believe. She commits herself to pressuring Congress to repeal the Santa ban. But how does a meek sixteen-year-old take on the federal government?

She seeks help from a band of outlaw SANTAS, who secretly meet in a condemned department store building. Together they devise an ambitious plan to challenge the powers that be, with Holly as their spokesperson. SHERMAN, a solitary teen like herself, is brought on board to write her speeches. Naive in matters of the heart, Holly is immediately drawn to the introvert-turned-activist.

The Bring Back Santa movement soon gains national attention. Holly appears on TV to promote the campaign's Christmas Eve rally. But days before the pivotal event, federal agents raid their secret headquarters. Holly suspects there is a traitor in their midst. As the lead investigator flips open his badge, a wallet-sized, family photo reveals Sherman, posing with his special agent dad.
