Documentary-maker Linda (Aniston) and finance executive George (Rudd) are an upwardly mobile New York couple who turn on, tune in...and fall out when they wind up living in a hippy commune.
They're stuck in a world of free love, 24/7 meditation and finger bells after Linda's latest doc is rejected by HBO and George's bank is closed down by the FBI.
Saddled with an over-valued Manhattan "micro-loft", the have to move out - but moving in with George's obnoxious brother and his hysterical wife is not an option.
Instead, they pitch up at Elysium, a past-its-sell-by-date, patchouli-drenched Shangri-la ruled over by passive-aggressive New Age sage and alpha male Seth (Theroux).
Despite their straight-as-a-die city backgrounds, Linda finds herself attracted to Seth's motivational, holistic back rubs and George is tempted by offers of free love from Malin Akerman.
Beatnik-bashing isn't the most difficult satirical skill to master and director David 'Role Models' Wain goes for his tie-dyed targets with no-holds-barred gusto.
Alan Alda is literally wheeled out as a disabled Woodstock veteran and there's some laughs to be had at the expense of Joe Lo Truglio's nude winemaker.
Rudd really lets rip, particularly with a sexually assertive monologue delivered to a mirror, and Aniston is game, even if she can't match her co-star's uninhibited verbal raunch.
Produced by Judd Apatow, it's an uneven affair but fans of the style will find it comedy nirvana.
