In the series premiere, billionaire industrialist Alexander Addington finds out from a source at the UN that Annie Morley, an old flame of his employee Peter Sinclair, has been kidnapped after her husband, Eric, reneges on a deal with a former CIA colleague involving triggers for sleeper bombs - the latest toys for terrorists. No one has reported it to the police and no investigation is taking place. Against this backdrop, the Counterstrike team swings into action with direct orders from Addington to intercept the deal before the transaction is completed.

Stasch Janic, who is Alexander's old friend, sends his daughter, Carmilla, who is a raising tennis sensation and Alexander's goddaughter, to a excellent tennis coach and a family friend after her old coach, Trevin, is stabbed after a tennis match, which Carmilla has just won. Alexander sends Stone and Sinclair to Yugoslavia with Stasch in the event that a death threat should actually be realised. At the same time, Gabrielle accompanies Camilla to her new tennis training campus ran by Vlad. During her stay, she discovers something very strange is going on and drags Sinclair and Stone back to New York once everything in Yugoslavia has been wrapped up. In the process of the investigation into Vlad, the team discovers that Vlad is involved in blood dopping.

Gabrielle attends a party in New York to celebrate the success of her friend, Quinton Jones, the artist. He tells her that his invitation is related to some information he has for her. The next day, Gabrielle wakes up in a daze to the knocking on her door. The police tells her at the station that Quinton Jones has been killed in an auto accident the previous night and believes she was the last person to see him alive. As a result, they want her to make a statement. Apparently, Gabrielle finds herself suffering from a total loss of memory of everything that happened after she got to the party. A rather desperate Gabrielle calls Alexander for help.
