In a small town in New England, Adam Sandler plays Davey, a bitter and disillusioned man who has lost the spark of life following the death of his parents. His erratic behavior and addiction to alcohol lead him into trouble, making him a pariah in his community. After a disastrous incident during a celebration, Davey is sentenced to perform community service at the local recreation center.
In his new "mission," he encounters a quirky group of characters, including elderly Whitey, a man with a heart of gold who tries to help him reconnect with his true self. As the holiday season approaches, Whitey and his lovable friends teach him unexpected lessons about the importance of family, friendship, and redemption.
With a musical backdrop filled with Christmas carols and a plethora of comedic situations, the spirit of the holiday season comes alive as Davey struggles to confront his inner demons. The festivities bring him moments of hilarity, reflection, and, of course, a lot of craziness. Amid frenetic rhymes and eccentric characters, Davey must decide whether he wants to remain the Grinch of his own life or open his heart to the magic of the festivities. With each challenge, he faces the possibility of a new beginning, as the town and his soul come together in a splendid holiday finale.
