While arguing with his girlfriend Kim, he is interrupted by the car park attendant Martin Lomax, who apparently comes to their assistance with a crowbar when they are locked out their car. When Martin begins staring at Kim, Ian gets aggressive with Martin and begins mocking him, which ends with Martin shooting Ian in the foot, then shooting Kim. Ian and Kim are knocked unconscious by Martin's crowbar, then bound and gagged with duct tape and loaded into Martin's van, as he intends to use them for his human centipede creation.
In Martin's warehouse, Ian is attached to Paul's buttocks and is in 5th place of Martin's 'centipede'. In the climax of Full Sequence, the centipede splits into two segments after one of its inhabitants rips his face off of another's rectum. When the two segments attempt to escape, Martin proceeds to kill each person out of spite. When he gets to Ian, he shoots him in the back of the head with his gun, killing him instantly.
