A behind-the-scenes documentary is shot in Bogota about the making of Medellín. During the filming, Eric and Billy clash over keeping filming on schedule but Billy's growing crush on Vince's co-star disrupts the schedule even more.

Now that Vince is back in America, Drama plans a welcome home party at his new place, but the party is anything but fun when Drama's obsession with tidiness gets in the way.

Billy submits “Medellin” to the Cannes Film Festival, Vince gets in over his head in Malibu and Drama rekindles an old romance.

Eric has to let down a Hollywood heavyweight, Drama fetes the mayor of Beverly Hills and Ari mishandles a top-secret script.

Eric feels Billy's wrath when the “Medellin” trailer turns up on the Internet, Ari and Lloyd scheme to secure Vince's next film and Drama goes to extremes to make a fashion statement.

Billy and Eric reconcile after their latest flap but their mutual distrust still simmers, Lloyd's love life interferes with his work and Turtle's cousin proposes a risky business venture.

Eric and Turtle's love lives become a source of amusement for Vince and Drama and Ari adjusts to having his son in public school.

Vince has his eye on a piece of antique furniture for Eric's new workspace and Ari is introduced to an R&B singing sensation.

Eric gets into a minor car accident with Anna Faris and thinks that they shared "a little moment" in the process. Turtle heads to the grocery store and picks up some provisions for a spur-of-the-moment party, but gets sidetracked in the process.

Ari is forced to work overtime when Billy delivers his script for Vince's next film and Eric has his hands full with a new client and her boyfriend.

The guys' trip to Cannes for the "Medellin" premiere is hampered by a security threat at the airport. Ari deals with his wife's and Lloyd's desires to go to France and Billy does his best to accommodate Eric's new client.

In the fourth-season finale, attempts to sell "Medellin" at Cannes are complicated by the fact that no one has seen the finished product. Meanwhile, the popularity of "Viking Quest" gives Drama a confidence boost.
