In Hawaii Sorcha and Agne are working in a deli. But when Agne gets a promotion it's the lunatics are running the asylum and they can do whatever they like. They generously start to feed all their friends back in the house. Later on they take an adrenaline fuelled tumble from a perfectly good airplane and see Hawaii from above. By the time 4th of July rolls around they have really settled in and Sorcha even gets invited out on a "date" by a local.
In San Diego cabin fever sets in, as all play and no work means living in the burbs is becoming too much. The group seems set for a split as Tim and Luke are getting out of the lease and heading for the beach.
Later the lads find a loophole in San Diego's drinking regulations and join a flotilla of drunk party animals for the craziest 4th of July of their short lives.
The Chicago guys are looking for something else and so Darren and Donal head off to do some volunteer work proving they do indeed have hearts. When they are not saving flooded villages they are making a fortune feeding the hungry Americans in a classy burger joint. But is the American dream (and the money) going to Eamonn's head?
