Following the failed voice over session, Martin is now jobless and doen an agent as Steven, depressed by his mother's death, wants time to himself. Neil, newly dumped by Jean, agrees to be Martin's agent and gets him a spot busking at the mall. However, he pales in comparison to the violinist and the human statue and is nearly arrested for not having a licence. Back home, Martin is visited by the revenue man regarding unpaid tax.
After suffering an ant infestation, Martin attempts to console a heartbroken Neil, who believes his lacking estrogen is at fault. Martin sees Steven off, who is travelling abroad, before going on a blind date Jean arranged with her friend Harriet. Despite the presence of a depressed Neil, the date goes well and Harriet loves Martin's mimicry, even encouraging it during sex.
Martin gets a job in site management at a deserted building but quits after discovering indigents sleeping there. He does, however, find a diamond ring that Neil's father assesses as being valuable. Whilst Neil sees a psychoanalyst to get over Jean, Harriet gets Martin onto the books of ventriloquist and theatrical agent Kingsley, though there is initial resentment from competing impressionist Nigel Lord.
Whilst Neil finds working out the perfect therapy, Martin opts to swap mimicry for stand-up but it's a disaster, finally redeemed when he switches back to impressions. To the dismay of the adoring Jean, he proposes to Harriet, largely to give Steven a family, telling her that the ring he found is a family heirloom. She accepts but on the condition he convert to Judaism, which involves him being circumcised!
Though his career is flourishing, Martin is perturbed by Harriet's enthusiastic wedding planning and, particularly, the prospect of circumcision. Harriet has Sunday dinner with the Hurdles, where Nan lets slip that the ring was in fact found in a drain. On his stag spa weekend, Martin meets Harriet's laddish, non-kosher brother Glen, who reveals that Harriet was recently dumped by Nigel Lord and that her possessive father is requiring the circumcision to put Martin off the wedding.
Against Jean's advice, Martin goes ahead with the wedding, financing it himself since Harriet's father has dropped out. Harriet, apparently more attracted to his impressions than Martin himself, criticises him, and on the way to the honeymoon, Martin makes the definite choice for his future.
