Documentary about the Apollo 16 mission, from April 1972, the fifth crewed Moon landing. It tells the mission from start to finish with period audio and footage, from the countdown to re-entry. The crew was made up of John Young as commander, Ken Mattingly in charge of the command module Casper, and Charles Duke in the lunar module Orion. The objectives were the scientific study of the surface, the use of the lunar rover, and the deployment of the ALSEP experiment package.

The countdown on April 16 included a planned hold and a check of a backup Saturn V gyroscope. During the flight, a short circuit knocked out the inertial platform. It had to be realigned using the Sun and the Moon, because paint flecks coming off the lunar module made it impossible to use the stars. Once in lunar orbit, an oscillation in the main engine's guidance system forced the landing to be delayed about six hours. Young set Orion down in the Descartes region, on the Cayley plains. To avoid losing surface time, the stay in lunar orbit was shortened. Meanwhile, word reached them from Earth that the House of Representatives had approved the space budget including the shuttle.

While deploying the ALSEP, Young accidentally caught his foot on the heat flow experiment's cable, which snapped beyond repair. On the first moonwalk, near Plum crater, they collected Big Muley: at 11.7 kg, the largest sample of the program. That same day they also filmed the rover's "Grand Prix," a test left pending since Apollo 15. The second moonwalk headed toward South Ray. On the third they studied House Rock, a boulder 12 m tall. The crew spent 71 hours on the surface and brought back more than 90 kg of samples. After docking, the jettisoned Orion began to spin and a year later crashed onto the Moon. That impact was recorded by the seismometer. On the way home, Mattingly performed a spacewalk lasting 1 hour 24 minutes. The mission lasted 12 days and made 64 orbits of the Moon.
