After a successful first mission, the unit get debriefed; McKenzie is carpeted for his actions while Gallagher has to inform Simone's mother of her tragic death. Tightrope walker Soltysyk 'Warsaw' is recruited.

Gallagher wants to be relieved of duty due to attrition rates among the recruits. Lovell starts playing up, causing friction within the group. Meanwhile, Merle and Ferdy start planning a future together if they survive.

The unit has now been reduced to six specialists who will participate in the raid. Lovell is determined to quit but no replacement can be found. His superior Professor Evans is brought in to help change his mind.

The unit enters France and discover, from Pierre, that the invasion is a mere two days away. The group head to the German rocket base in Deauville. An RAF bomber raid causes the power to go out, allowing the unit to get in.

The unit have reached the heart of the rocket site. The German kommandant has been made aware that at least three men are on the premises. The group find the documents and plant their bomb but have just sixteen minutes to escape.
