J.T. Forbes is tickled pink when informed he finally won a prestigious scientific award, but it's a ploy to lure him to a dungeon, where he's imprisoned with another researcher, who failed to reproduce the Muifield beast formula, which he fears won't save their lives anyhow. After Vincent discloses to Cat they're after the same collar, only it's not a regular Chandler heirloom jewel but a beast control collar, they team up again, plus FBI agent Dana Landon, coordinated by Gabe, despite the end of his professional assignment to Cat's precinct. Tori gets jealous and is kidnapped before Vince can trace the dungeon for a showdown, with a fatality and J.T.'s fellow prisoner's identity as last shock.
