Things were peaceful in Trollstopia after Trolls World Tour, but then a wolf comes to Trollstopia and then one of the trolls gets bitten, but doesn't notice they're curse, at day they're normal, now by night they will go through a new experience of being a weretroll and gets into a lot of trouble, it's up to Poppy (Anna Kendrick) & Branch (Justin Timberlake) to find a cure to fix the trolls before they stay a weretroll forever, they'll meet new friends along the way but sometroll will want to kill the weretrolls for what they did in the past, do you think Poppy & Branch will save all the trolls from being a weretroll forever?
