Eva and Frost are pretty stoked about their blooming hunting skills, but when they finally meet Raylan's sister, Tess, after a witch doctor hunt in New Orleans, the group dynamic gets rather awkward. Tess wants to kill Knox straight up dead. As in, drag him up from the bottom of the old mine shaft and use Tess' favorite snake from the Louisiana bayou to finish the job. Eva loves the idea of bonding with Tess and being extra sure Knox will never come back to harm them, but Maggie ain't thrilled at the idea, and Frost is a little distracted by her new cowboy boy-toy. When Tess gets attacked by the Despairity, Eva and Raylan race back to New Orleans to help. Maggie isn't answering her phone, and what Tess shows Eva in her secret basement is something no one expects, and it's gonna test everyone's relationships. The hunters have to decide where their loyalties lie: family, friends, or love.
