Led by Ashley Hunter-Coddington (Catherine Oxenberg), a former MI6 operative, and Mike Savage (Brendan Kelly), a former CIA agent, the H.E.A.T. members fight international terrorism and crime. They receive their assignments from Mr. Smith (John Vernon), the mysterious head of C-5, a clandestine government organization linked to the United Nations. The team operates throughout the Caribbean and around the world under cover as fashion models and photographers. The team members are Catherine "Cat" Avery Pascal (Alison Armitage), a former cat-burglar, who had to choose between life imprisonment or working as part of H.E.A.T. for a year learning their values, Tommy Chase (Michael Worth), the martial arts expert who has a deep understanding of the human mind, Brett Richardson (Spencer Rochfort), a former Navy SEAL, with a vast knowledge of explosives, Krissie Valentine (Holly Floria), the computer genius that can do anything with computers no matter the situation and who eventually is involved with fellow team member Marcos, Marcos Chavez (Randy Vasquez), a member of Los Federales and whose contacts in Mexico provide a much needed help, Arthur Small (Graham Heywood) who deals with the teams logistics and manages the "facade" of the Beach Fashion Enterprise and Claudio Divanti (Fabio), the owner of the hotel where the team has its headquarters.
Catherine ("Cat") Avery Pascal and Tommy Chase, are the only original team members to return in the second season. The team disbanded a few years after the first season. Cat became a beach fashion photographer and Tommy became a lone wolf. They were contacted by Nicole Bernard (Lydie Denier), an ex-spy and Joanna Barnes (Christa Sauls), Nicole's protégée and a computer expert. They continued fighting international crime backed by private investors and undercover as owners of a beach fashion boutique, called "Acapulco HEAT Beach Fashions".
