After investigating a strange cluster of female deaths and disappearances, Nick (David Giuntoli) sends Monroe (Silas Weir Mitchell) undercover to get a whiff of a hypnotic suspect. In the meantime, a stranger shows up looking to avenge the death of his friend at the hands of a Grimm, but he’ll have to get past Captain Renard (Sasha Roiz). Russell Hornsby, Bitsie Tulloch and Reggie Lee also star.

Following the massacre in Nick's (David Giuntoli) loft, Capt. Renard (Sasha Roiz) is hell bent on eliminating him once and for all. Hank (Russell Hornsby) and Wu (Reggie Lee) head back to the precinct to keep an eye on the Captain and help give the gang the upper hand. Meanwhile, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) grapple with staying in Portland now that their family will be expanding. Elsewhere, Eve (Bitsie Tulloch) suffers the side effects of the mysterious stick's healing power.

Nick (David Giuntoli) faces off against his greatest foe yet as it seems no weapon can defeat him. At the Spice Shop, Monroe (Silas Weir Mitchell), Rosalee (Bree Turner) and Eve (Bitsie Tulloch) search for answers and stumble upon a rare potion that may help the fight. Elsewhere, Capt. Renard (Sasha Roiz) and Adalind (Claire Coffee) try to keep Diana (Hannah R. Loyd) and baby Kelly safe as the threat has its eyes set on the children.

Hank (Russell Hornsby) and Wu (Reggie Lee) find a solution to stop Renard (Sasha Roiz) while Nick (David Giuntoli) is still on the run. Adalind (Claire Coffee) receives a phone call that throws her into the middle of everything. Back at the spice shop, Monroe (Silas Weir Mitchell) and Rosalee's (Bree Turner) adventure in babysitting takes an interesting turn when Diana (guest star Hannah R. Loyd) demonstrates her power. Meanwhile, Eve (Bitsie Tulloch) and Trubel (guest star Jacqueline Toboni) work to solve the mystery of the cloth found with the healing stick.

Nick, Hank and Wu investigate a terrifying new Wesen who terrorizes a young family and has a surprising motive. Capt. Renard is reeling after an unexpected guest appears. Meanwhile, Diana has some interesting news for Monroe and Rosalee. Elsewhere, Eve returns to the catacombs beneath Nick’s loft to search for answers to her bizarre visions and side effects from being healed by the mysterious stick.
