Lilli Masters has a choice: join her brother in Peru to photograph butterflies or join Zack Faraday, the love of her life, in Daytona Beach, Florida, to photograph Harley Davidson bikers. She chooses love and the adventure begins.

Picking up where the relationship left off in Grayrocks, Long Island, Zack and Lilli head to Florida under the pretense of a married couple visiting his sister. However, Detective Zack Faraday is there undercover to investigate the whereabouts of Benjamin Voda, a cold-blooded killer who is wanted in New York City. Zack is also in Florida to patch up his relationship with his sister, who is confined to a wheelchair after an accident.

Almost immediately, a ruthless crew of men begins stalking and threatening Zack, Lilli, and all their new friends in Florida. They find themselves swept up in the unusual yet dangerous world of bikers, orchid collectors, alligators, and murder.
