Crimson loves to dance. He adores watching the pretty boys grind to the frantic beat of the music and picking out his lover for the evening. But more than that, he lives for his birthday, that one day a year he gives into his darker impulses: choosing a young man to lure into the alleyway with promises of sex, then slitting his throat in the midst of their passion and reveling in the hot blood on his hands.

For Tracey Winston, life has become a nightmare. Kidnapped from a nightclub in Boulder, Colorado, brutalized and raped by Crimson, he’s held captive in a cabin in the Rocky Mountains along with sweet Kyle, a young man Crimson keeps chained to his bed and is slowly torturing to death. Though Tracey manages to escape with Kyle’s help, he has to leave Kyle behind in Crimson’s cruel hands.

Detective Gene Mallory has never stopped looking for his brother Kyle, kidnapped from a nightclub seven months previously. The case breaks open when Tracey Winston comes forth at the urging of his new boyfriend, claiming to have knowledge of where Crimson is hiding out. A manhunt begins with Crimson continuously slipping through their net. Lives are on the line, with both Gene and Tracey being targeted by the killer. A traitor in their midst tips Crimson off to their plans.

Crimson’s birthday has come and gone, and he will kill again.
