In this heartwarming gem, Rhode Island State Trooper Dan O’Neil (Grant Gustin, above) adopts Ruby, a shelter dog who is about to be put down, so the two can try for a spot on the K-9 search and rescue unit.

Both are, yep, underdogs. The restless O’Neil is a good cop, but his boss thinks he lacks this gig’s requisite calm. And mixed-breed Ruby isn’t a German shepherd, which the squad prefers—plus, she’s naughty. O’Neil’s aha moment comes when he realizes Ruby, like him, doesn’t excel in traditional schooling. So he creates an individualized training regimen, and both thrive.

“Daniel has to focus on trusting his heart and his strength, rather than fighting his frailties,” Rescued by Ruby director Katt Shea says. The dream team proves their worth in a stormy search for a lost child.
