Seeing Lau's van pull up outside the office Phil sneaks in and frees Scarlett and he and Sam take her to Phil's house where Linda, Phil's mum, mistakes her for Phil's girlfriend. They then return her to Stevens but she is so angry with him she hits - and accidentally kills - him, ungratefully telling the police on the phone that Phil and Sam were the culprits. They flee again and are saved by agent Walker, who is seeking Russian spy Marat Malankovic, and seems to think the lads are involved. Stevens is killed by double-crossing fellow agent Smoke and, opening his car boot, they find huge sums of money, plus the man he stunned and abducted, who also mentions Malankovic before running away.

Sam gives Scarlett the music box but Phil has discovered why she was so desperate for its return. In it is hidden a memory stick which shows her having sex with transport minister Ian Culverson in order to blackmail him into approving an unpopular land deal which will make her father wealthy but leave Lizzie to take the blame. Following their involvement with two murders and deal with Lau the boys attract the attention of MI5 boss Ms Cox, who sends agents after them. Smoke kills Malenkovic before, accompanied by several of his colleagues and a helicopter, pursuing Phil and Sam.
