Steve feels inadequate when hunky Rob flirts around his girlfriend Michelle, and goes too far trying to prove they might be sleeping together.
He tracks the couple down as they take an over-night business trip to Sheffield. But Steve's idiotic plan backfires with disastrous results.
Simon Gregson, who plays Steve, said: "Although something is afoot, it isn't quite what you think, but I can't tell you what happens!"
Watch the exclusive interview with preview clips of Steve's plotting against Rob.
