This evening, fans will see Rhys and girlfriend Jacqui (Claire Cooper) face a desperate race against time to pay off a debt they owe to dangerous Danny Houston (Darren Day) after a plan to scam him in a poker game goes wrong.
Issuing a sinister threat to the couple, Danny insists that they must pay him back within 24 hours - or else Jacqui will have to spend the night with him.
Speaking to Soaplife about Rhys's predicament, Moss commented: "He loves her and would rather die than let her sleep with Danny. Rhys will do whatever he can to find the money."
Following some advice from his boss Brendan Brady (Emmett Scanlan), Rhys teams up with Gilly Roach and they target Danny's glamorous drugs runner Sophia (Donna Air) in a robbery attempt.
Moss continued: "It seems Brendan wants to screw over Danny and be top dog in Hollyoaks again. The idea is that Brendan will set up a drugs deal, then Rhys and Gilly - armed with a fake gun - will hijack the drop-off and grab the cash."
However, the plan to raise the funds by paying Danny back with his own stolen money suffers a hitch when the gun turns out to be real and Sophia turns the weapon on Rhys and Gilly.
"As the 24-hour deadline arrives, they're all in desperate trouble," Moss confirmed. "Jacqui's being forced to strip at knife-point, Sophia is holding Rhys and Gilly at gun-point and it seems there's no way they can win. Rhys is really pushing his luck this time and there's every chance one of them might not make it back to Hollyoaks alive."
Hollyoaks: King of Hearts airs tonight at 10pm on Channel 4.
