The end is near for M. Night Shyamalan’s Servant on Apple TV Plus. The final season kicks off in January, promising to finally reveal what in tarnation has been happening in the Turner household since the arrival of the mysterious Leanne Grayson. 

For those who aren’t familiar with the series, Servant started out with a husband and wife who hire a nanny to watch over their son, Jericho. It turns out though, that Jericho died tragically months prior and the wife has no memory of it. But when a mysterious nanny arrives things start taking a very odd turn. 

Servant is delightfully dark and full of Shyamalan’s trademark wit, along with the twists and turns you’ve come to expect. 

We previewed the first three episodes of the season and there's no question that Servant gets off to a great start with some of the most sinister happenings we've seen yet. There's a shroud of mystery over the house as Dorothy returns from the rehabilitation center after the fall she suffered at the end of season 3. Leanne is as concerned as ever that the Church of the Lesser Saints is close to finding her, and she lashes out. 

As with other seasons of the show, the sound is what really sets this series apart from most. You can close your eyes and appreciate the series purely based on the sound alone, from sound effects to the score. It's a real treat for Shyamalan fans and fans of solidly written horror. 

Here’s everything we know about Servant season 4.
