[2] Based on a true story, it follows State Trooper Daniel O'Neil (played by Grant Gustin), who dreams of joining the K-9 search and rescue team.

Ruby is an extremely hyperactive half-border collie that has been adopted seven times from the shelter she has been in over the last six months, but always later returned due to an inability to train or control her.

Daniel learns that the K-9 unit has no funds to import any more German Shepherds, the breed usually used in search and rescue teams, and therefore he would not be able to join the program.

He finds out his wife Melissa is pregnant with their second child, making him even more determined to go for it because the promotion would also improve his pay and benefits.

Sent to a home where a murder victim is meant to be, Ruby senses human remains, but Dan can't find them.

She runs off during the night, only to have Zarella tell him the remains were found at the scene where Ruby indicated, but buried beneath concrete.
