ASIO enlists a couple of the Water Rats in a covert operation which causes Reilly to become the victim of an amorous spy and Sykes' love life gets him into very hot.
The Water Police concentrate their efforts on locating two young girls believed to have been abducted while on their way to school. Sykes and Reilly are recruited to work alongside two agents from the Australian Security Intelligence Organisation on a seemingly innocuous surveillance job which ends in Mick facing a charge of sexual harassment.
