Who's ready for some family drama?

Supernatural star Jensen Ackles is set to guest-star on a new episode of Tracker as Russell, Colter's (Justin Hartley) estranged brother. The episode, titled "Off the Books," sees Russell ask Colter for help finding a former army buddy who's gone missing — or should we say, who hasn't been home in a few days?

Entertainment Weekly has an exclusive sneak peek at the episode, which features a fireside chat in which Russell asks for his brother's help, and the two of them start trying to piece together the whereabouts of the missing person. Although Colter is willing to help, it's clear from the conversation that these two don't have the closest relationship.

According to the episode description, the investigation will take the brothers into the world of "Special Forces missions, shady off-the-books programs, and conspiracy theories, all while they contend with their family's past." Good thing Ackles has a lot of onscreen experience with complicated investigations and even more complicated family dynamics.

Tracker airs Sundays at 9 p.m. ET/PT on CBS.
