The kids discover Mr Klausen has burned the script for the local Christmas play and is planning to put on his own show, during which he will steal the money from the church’s Christmas Eve collection. Luckily, The Tower Agents are at hand to save the day.

Unexpectedly, they get help from a mysterious and powerful key that allows them to move back 2000 years in time. They meet historical people from the biblical Christmas story that inspire them to create a new Christmas play. This play might allow them to take the stage before Mr.Klausen, and hopefully save the Church’s money.
