THE story begins with David Clark, played by Jennifer Aniston’s good pal Jason Sudeikis, a small-time drug dealer with small-time clients – think housewives or chefs (but no kids because he has scruples).

When a good deed goes wrong and his attempt to save a homeless girl (Emma Roberts) from being mugged results in his stash and cash being stolen, he’s forced to settle his debts by picking up what his boss, Brad (Ed Helms), describes as a “smidge” of drugs from Mexico.

However, if he’s to make it across the border in a motorhome without raising suspicion he’s going to need a fake family to keep the sniffer dogs off his scent, so he seeks help from his neighbours, stripper Rose (Aniston) and geeky teen Kenny, along with streetwise Casey (Roberts), to look like any other all-American family.

As they take to the road in the obscenely large motorhome dressed in nice middle class clothes with sensible haircuts, they might look the part, but it’s not long before the dysfunctional group gets into all sorts of scrapes, especially when it transpires that the “smidge” of drugs is, in fact, millions of pounds worth of pot which fills every nook and cranny of their vehicle.
