Eugene Jones is having a rough day. He wakes up in the middle of a road, gets up, and walks over to the Torchwood crew investigating nearby. He notes they seem to be ignoring him and are busy examining a body. Eugene's body, to be exact. Eugene comes to the realization that he's dead and no one can see him.
Backing up a bit, we go into Eugene's childhood and learn how, during a maths competition, he ended up having a bad day and letting his team down. His father was furious, but one of his professors took pity on him and gave him an object that fell out of the sky near him when he himself was having a bad day at golf. The object appears to be an eye with swirly... things inside. That night, Eugene's dad leaves his family.
In the present day, Eugene has become an alien enthusiast, obsessed with learning if there are really aliens. He attempts to get Gwen's attention to show her his items. Despite being unable to get her attention, he never gave up, right up to his being run over by a car. Although Torchwood brings Eugene's body into the Hub for autopsy (Eugene's "spirit" following closely behind), they then learn that the traffic accident was routine and they leave it.
As Eugene trails Gwen, who can't shake the feeling that there was something more to his death, he finds he may be able to subtly suggest her actions. He says "phone Gary", which she does, for example. Through Eugene's mobile pictures of random shoes, she manages to track down Gary at the place they both worked. From there, she finds another colleague of his, Linda, who explained that Eugene was going to sell the eye to give her money to go on a trip to Australia. Things got interesting when the auction bid ballooned to over £15,000.
Working from that interest in the eye, Jack tells Gwen that it could be a Dogon Sixth Eye, which there's a market in. Tracking down Gary, Gwen learns from him that he actually inflated the bid himself, at first. Then, when the bid jumped to £15,000, they knew someone else was involved. A few clues and suggestions later led to a restaurant and Eugene's friends, who sniped the 15,000 bid, admitted to the gag, and then revealed that they decided the original big bidder, who is just a regular human, could be coerced into much more. After learning that aliens are not behind it at all, Eugene flips out, swallows the eye — which, it seems, caused his ghostliness — and runs off from his friends, which is when he gets accidentally run over.
Still, after this mundane solution to everything, Eugene is able to find peace and closure when his father attends his funeral. The eye had given him a chance to appreciate what he had. At the finale, Gwen is about to get run over by a car, which Eugene saves her from by suddenly turning solid and visible. He and Gwen are able to exchange thanks (and the episode's requisite kiss) before he passes on for good.
