Clean Skin (S02E07)

A rogue French scientist has absconded with a highly classified weapon known as Firestorm and is looking to auction it off to the highest bidder. Now hiding out in the UK, MI5 finds itself collaborating with French Intelligence. The British, however, are determined to acquire the technology for themselves. To pull this off discreetly, they enlist an agent with no ties to MI5. Just when the plan seems to be in motion, a break-in at Harry's apartment threatens to unravel everything. Or could it be a blessing in disguise?
