Frank and Luella are employed by Bertie Tark, CEO of high tech company Forosa, to find a mole leaking secrets of a new fashion app about to be launched. Their old computer geek friend Spider, who acts as head of security, recommended Frank and Luella and together they investigate the employees who present a happy front despite the head of development, Dean Parolles, being an overbearing taskmaster. When Parolles is murdered suspicion falls on employee Helena Mau who claims to have invented the original app, but Spider who has fallen for her is convinced she is innocent.
