Final Flight of the Osiris (2003) on Netflix

Plot summary

Aboard the hovercraft Osiris, a sparring session between the senior officers, Thaddeus and Jue, is interrupted when the crew spots a threat to Zion, the last human city. A quarter of a million sentinels are digging up through the earth's surface toward it. The crew decides to carry a warning home to the settlement, but the machines detect the ship almost at once and the pursuit begins. Jue's way to reach Zion is a broadcast drop into the Matrix, and there she can send the message while her comrades aboard the Osiris hold off the enemy as long as they can.
