With the score tied at 47 and six seconds left on the 30-second clock, Peoples stepped back behind the 3-point line and swished a hop shot to put Arkansas up 50-47 with 42.3 seconds left.
The Lady'Backs added two free throws by Kristin Moore and one by April Seggebruch, then blunted Indiana's last possession to beat the Hoosiers 53-50.
"They had been playing off me all night, so I took a jab step and shot it," Peoples said. "It looked good all the way."
Her jab step was off her right foot -- her good one.
"My left foot has a rash that's out of control," Peoples said. "I had put medicine on it and then I went tanning. That affected it. You don't want to see it."
There were parts of the game you didn't want to see, either.
Arkansas (5-1) went 11 minutes, 40 seconds without a field goal at one stretch, and Indiana (2-2) went six minutes without scoring at all in another.
But Sarah Pfeifer, who matched her career high with 13 points for Arkansas, offered a reason for the droughts.
"Indiana was big and physical, and Ruby Vaden was big and physical for us," Pfeifer said.
Vaden got all 10 of her rebounds in the second half for the Lady Razorbacks, who overcame a 32-27 halftime deficit.
"Ruby stepped up for us," said Arkansas coach Susie Gardner.
Arkansas missed 13 floor shots in a row at one point, but atoned by not turning the ball over in the final 9:28, while Indiana was committing eight of its 19 turnovers.
Indiana coach Kathi Bennett said the Hoosiers "did a horrendous job of defensive rebounding" while Arkansas was rallying in the second half.
Guard Adrienne Bush, just 5-foot-8, had one of Arkansas' biggest baskets -- a follow shot in traffic to tie the score 45-45 with four minutes left.
Then Danielle Allen, who had missed five of her first six field goals tries from point-blank range, made a layup for a 47-45 UA edge off a feed from Rochelle Vaughn.
After Peoples' bomb gave Arkansas a 50-47 lead, Allen took a charge against Leah Enterline on the other end.
"That was a huge play by Danielle," Gardner said.
With 25 seconds left, Moore (0-of-7 from the field) made two free throws that brought a smile to Gardner's face.
"Kristin had a tough night, but she stepped up and hit those two shots," Gardner said.
Arkansas led 52-47, but Nikki Smith complicated things by making a 3-point bank shot with 16.3 ticks to pull Indiana within 52-50.
Seggebruch made the first of two free throws for 53-50 with 15.9 seconds left, and Indiana botched a late attempt to work for a 3-point shot for Cyndi Valentin, who finished with a team-high 14 points.
"We did get a double screen, but our pass got deflected (by Vaughn)," Bennett said. "Arkansas did a great job of defending the 3-point line."
The Lady'Backs defeated Indiana 78-70 at Indiana last season.
"They were pretty one-dimensional then," Bennett said. "Shameka Christon was a scoring machine. We put three people on her and she jumped over us. Tonight Arkansas ran a nice high-low game, and Peoples did a nice job of staying under control. She hit a tough shot, too."
Gardner said she thought Arkansas rushed its shots in the first half.
"We were so wide open, we were surprised at times," she said. "Game speed is faster than practice, and we need to calm down a little."
Vaughn made 3-of-5 3-point shots and scored 11 points in a team-high 34 minutes.
