The Woodside basketball team inadvertently summons an ancient Highlander warrior; Gretta and Baldric must come to Dwight's aid as he has fallen ill and cannot perform his duties as Woody the Woodchuck, Woodside's mascot.

Dwight agrees to help Gretta host an ancient version of Thanksgiving; an infinity spell causes them to live the same day over and over until they accomplish everything correctly.

Due to a magical birthday tradition, Chlodwig and Dwight switch bodies for the day; Gretta and Baldric try to aide the body swapped heroes as they venture through their days as one another.
