A mutiny aboard Enterprise NX-01 in 2154, led by Trip Tucker and T'Pol, after an alien toxin drove Captain Archer to endanger the mission in order to protect a nest of Xindi-Insectoid eggs.
In the Enterprise episode Hatchery the crew find a crashed Xindi-Insectoid ship with a chamber of unhatched eggs. An egg sac sprays Archer with a substance that makes him imprint on the young as a guardian.
Archer diverts antimatter reserves to keep the hatchery alive, relieves T'Pol of duty when she objects, confines Reed to quarters after he fires on an Insectoid ship, and hands tactical command to Major Hayes of the MACOs.
Tucker, T'Pol, Reed and Phlox conclude that the captain is unfit and take the ship back, with some of the MACOs resisting them. Tucker stuns Archer in the hatchery, Phlox clears the toxin from his system, and no charges follow. The affair sharpened the existing friction between Reed and Hayes.
