The team attend a major road traffic collision where Stuart takes the radical decision to give an open-heart massage to jump-start a woman's heart. Back at A&E the lads feel the effects of the shock and adrenaline and are forced to see the hospital counsellor. Attractive new counsellor Kirsty, played by Morven Christie, advises them that they'll start out feeling fairly euphoric, may grow restless, but ultimately become depressed. Stuart gives his own take on this, and then pledges to control his predicted mood swings, but will he succeed?
Stuart, Rachid and Ashley find their male pride rattled by the lads from the local fire brigade. As the team make a drop-off in A&E, Stuart observes the waiting room is awash with the dregs of humanity and proclaims he's proud that he is 'biologically incapable of adding to its vile and dirty ranks'. Yes, he's firing blanks. When Ashley and Rachid tease him that he's not getting any anyway, he drops a bombshell; he has a date - with Angie, played by Charlene McKenna, a student and eco-campaigner he met a few weeks back. As soon as he's alone, Stuart digs out her number and quickly arranges the date. After a shaky start, things are going well with Angie, but Stuart seems to be behaving in a macho way that neither he nor his friends recognise. Is it Angie's mystique that's having this effect on him, or is it something more powerful than that?
The paramedics are called out to a young male in a student house who is suffering from drug-induced paranoia. When Rachid goes to talk with a neighbour, he comes across a scary 'purple job'; a suicide victim who has been dead for some time. The realisation that 'Purple Phil' wasn't missed by anyone for a fortnight sets off an unlikely chain reaction for ladies' man, Rachid. Convinced he doesn't want to meet his maker in similarly lonely circumstances, Rachid decides there is only one course of action - he needs to settle down. Only thing is, he's got to find the girl to do it with...
When Woodvine, played by Annie Hulley, threatens to split up the lads, Stuart's promise that 'his' crew will up their game sparks an immediate challenge to his leadership from Rachid. Stuart may believe that the alpha male is the cleverest rather than strongest member of the pack, but will Rachid's determination to prove him wrong cost him his crown? Meanwhile, Ashley has an alpha male secret of his own, while Maxine tries to bring out her feminine side to appeal to internet date Derek, played by Graham O'Mara.
Stuart is in denial about the stresses of his job so decides to focus on Maxine's unsettled feelings about fireman Craig, played by Ben Batt, and how they're threatening her chances of promotion. Although he attempts to find subtle ways to reassure Maxine that Craig is really into her, is Stuart really the right man to play Cupid, or will he end up creating more stress for both of them?
Stuart is hit hard by a life-or-death situation and he needs help from somebody to see him through it. With Maxine pre-occupied with fireman Craig, there is nobody he can turn to. Rachid's future on the team is put in doubt. Ashley is surprised to discover that he has suddenly gained a live-in boyfriend.
