Monkey Kingdom is a 2015 American nature documentary film directed and produced by Mark Linfield and Alastair Fothergill and narrated by Tina Fey.

[5][6][7] In the ruins of an ancient city in the jungles of Polonnaruwa in Sri Lanka, Maya is a toque macaque who was born at the bottom of the social order tree in her family.

One day, during the courtship season, a handsome male monkey named Kumar arrives & catches Maya's gaze from just outside of the troupe's territory.

Maya searches for hours for her lost child, frequently calling out to him vocally, until finally, the two are reunited, bringing the traumatic separation to a happy end.

With the humans away and oblivious to the macaque's break-in, Maya and her cohorts gorge on birthday cake, bread, fruit and all other manner of food.

The lowborn return to the troop's home in the forest, a granite outcrop called Castle Rock, and they fall asleep with an unfamiliar sensation: full stomachs.

Kumar is given an opportunity to further ingratiate himself with the troupe and prove his loyalty to Raja when a rival troop, led by Lex, comes to invade Castle Rock and take it as their own territory.

Despite putting up a good fight, Raja, Kumar, the Sisterhood, Maya, Kip and the entire troupe lose the battle and retreat.

The troop spends time in the city, rebuilding their strength, filling their bellies, and sleeping high on utility poles, but they never lose their desire to return to their home, Castle Rock, and reclaim it as their own.

Monkey Kingdom's major toque macaque characters consist of lead female Maya, her newborn son Kip, the troupe's alpha male Raja, a trio of high status females called The Sisterhood, Grandpa, an elderly but once-fierce male, and Kumar, a newcomer wishing entrance to the monkey tribe.
