Stella is getting ready for her date with Sean, which means, of course, trying to lose weight by joining in with the youth rugby team, when she learns Dai is in trouble, and has gone missing.  The race is on to find him.  Meanwhile, Ben has a secret he's now terrified of revealing to all the family....

It's Luke's 25th birthday, and while Stella is all loved up with Sean, the birthday boy doesn't know what to do about the return of his father, Rob Morgan.
