Baxter Thwaites is the Governor of one of the last outposts of the British Empire - Cascara, a small Caribbean island where the inhabitants spend their days smoking grass. Then an unexpectedly lucrative discovery is made - a gusher of ultra delicious, natural mineral water. There's uproar to the max as a motley crew of challengers all vie for control of the sparkling gold - including Thwaites' hot-blooded wife, a Texan billionaire, a sexy activist, a Rasta DJ, a singing revolutionary, Cuban advisers, U.S. 'peace-keepers', arrogant Frenchman and a representative from Mrs. Thatcher's government! Also stars Valerie Perrine, Jimmie 'J.J.' Walker, Fred Gwynne, Brenda Vaccaro and Dick Shawn; and guest appearances by George Harrison, Eric Clapton, Ringo Starr and Ruby Wax.
