The boys attend the Sundance Film Festival, in snowy season. Eric makes friends with golden touch-producer Harvey Weingard, who might buy Vince's movie, but actually wants him for an old project 'Tapping the Source'- he's hired on the spot for his Australian shooting in three weeks, but that would mean missing out on James Cameron's movie. Ari and E accept this 'safe bet', Vince decides otherwise- Harvey vindictively cries eternal doom. Drama hopes to land a part with his Spanish idol Alejandro Teva- by asking clumsy questions after his movie's screening, and still is offered an audition. Meeting peace Corps girls gets even Turtle horny enough to Google about their target country Sudan, rivaling for one with Drama; they get a threesome but 'cross swords'. Cameron walks out after only 10 minutes, but calls...

On the Aquaman set, Vince admits to his co-star Mandy he's still in love with her, which director Cameron hears trough their mikes and so does E, whose confidence is shocked by all his secrecy. Ari Gold, Vince's Jewish agent, is holding a bat mitzvah for his daughter Sarah; as usual he's frantic about his guests, such as his senior partner Terence McQuewick and his daughter Sloan, who is reputed to have an infallible eye for male acting talent and really digs Vince, so Ari fears Terence wants to 'steal Vince'. The boys carefully get fancy party dress at Vinces expense, except E who pays his own clothes and refuses to waste good money on labels like Armani; when he meets Sloan, he does dress up, making the others warn him he's setting himself up for another scorned crush. Drama and Turtle get stuck on an old peoples table and regret having eaten little before the party as they don't get to the yummy stuff having missed the synagogue service with appetizers, nor knew they had to order, so it's kosher vegetarian leftovers, till a waitress shows them the kids buffet, just what they wanted, but are startled to see 13 year-olds blowing weed. Mandy tells Vince she's not quite over him either and put her fiancé Chris on hold.

When Ari and E learn about each-others problems with Terence viz. Vince, both of which make the press, panic is total. Drama and Turtle give Vince the cold shoulder, hoping Saigon and his friends are their new meal-ticket. Even E considers taking a job as agent with Terence and moving in with his daughter Sloan. Vince refuses to reconsider bailing out on Aquaman and fires Ari and the entourage, yet turns up at Turtle's company birth party. Ari's successor Adam Davies tells Drama he's out with Vince. On Ari's advice, E still supports Vince who has scheduled a meeting with Cameron, whose enthusiasm pulls him over.

The night of the Aquaman premiere draws close and the crew is preparing themselves for the biggest event of Vince's career. Drama and Turtle keep finding better looking women to bring to the event, but they find themselves prematurely running out of passes to hand out to the hotties. Vince is less concerned about finding a date. He knows there's only one woman to bring -- his mom. Mrs. Chase is hesistant to make the trip to the West Coast due to a fear of travelling, but E finally convinces her to travel with both his and Turtle's mothers. Meanwhile, Ari adjusts to life in his new office (complete with broken down elevator) and finds that he's in for a huge challenge on his own.
