Sergeants 3 was the last film to feature all five members of the “Rat Pack”.
Set in Indian Territory, in 1870. Mike (Frank Sinatra), Chip (Dean Martin), and Larry (Peter Lawford) are three buddies who are sergeants in the U. S. Cavalry.
Larry’s time in the army is nearly up, and he is determined to leave and marry the beautiful Amelia. Mike and Chip are equally determined to prevent him from leaving. The three cronies befriend a former slave, Jonah Williams (Sammy Davis Jr), who dreams of someday joining the army.
A tribe of Indians begins terrorizing the region, and Chip decides to attempt to capture of their leader. Chip and Jonah sneak into the Indians’ secret meeting place but are discovered, and Chip is taken prisoner. Jonah, however, escapes and races back to tell Mike and Larry.
Larry decides to rescue Chip, but first Mike makes him sign a reenlistment paper “just to make his help official”. Mike promises to destroy the paper after the mission. Mike, Larry, and Jonah make their way to the Indian camp, but end up as prisoners.
The Cavalry is riding into a trap where a thousand warriors are waiting to ambush them, but Jonah blows the regiment’s favorite tune on his trumpet as a warning. The battle ends in victory for the Cavalry, the three buddies are decorated, and Jonah is made a trooper.
Afterwards, thinking he is discharged, Larry drives off in a buggy with Amelia. But Mike shows the commanding officer the signed reenlistment paper, so Larry will be forced to serve another hitch with Mike and Chip.
