Nicole and Natalie Appleton and Melanie Blatt of pop group All Saints make their acting debut in David Stewart's swinging Sixties crime caper. Sisters Gerry (Nicole), Mandy (Natalie) and Jo Chase (Melanie) hold up a Carnaby Street jewellers disguised as men. Gerry is the last to get away, and is caught and unmasked next door in the offices of 'Zero' magazine by aspiring journalist Daniel Wheaton (Peter Facinelli). Rather than turn Gerry in, Daniel puts her up for the night. Meanwhile, mob boss Duggie (Corin Redgrave) has worked out who was responsible for the hold-up, and is hot on Gerry's trail. Matters become more complicated still when Daniel's boss, Andrew Pryce-Stevens, arrives at his flat, feeds Gerry a cake filled with hallucinogenic drugs and helps himself to the stolen gems!
