CBS has renewed “Tracker” for a second season.

Based on Jeffery Deaver’s novel “The Never Game,” the series stars Justin Hartley as Colter Shaw, a lone-wolf survivalist who roams the country as a reward seeker, using his expert tracking skills to help private citizens and law enforcement solve mysteries while contending with his own fractured family.

The series premiere aired directly after the Super Bowl — which Nielsen measured as the most-watched telecast of all time — and reached 18.4 million viewers, a number that Paramount Global says has now grown to 30 million across platforms. Three more episodes have aired since, and continue to perform strongly without football lead-in: Episode 2 hit 6.9 million viewers, Episode 2 hit 7.1 million and Episode 3 hit 7.4 million.

The series was created for television by Ben H. Winters, who executive produces alongside Hartley, Ken Olin and Elwood Reid. Deaver serves as producer. 20th Television is the studio.

“’Tracker’ kicked off our premiere week with a ratings bang and has kept the momentum going,” said Amy Reisenbach, president of CBS Entertainment. “We knew we had something special when we saw the very first cut of the series and the overwhelming audience response confirms it. We couldn’t be more grateful to Justin, the talented cast, the incredible writing and producing teams and our partners at 20th Television for such compelling episodes. And, of course, we’re also so thankful to the millions of viewers tuning in each week.”
