This is quite a clever, well paced crime-noir with a really rather good performance from John Payne as "Joe", a former soldier/ex-con who, whilst on his routine flower-delivery rounds - ends up getting framed for a massive armed robbery. Luckily for him, the police can't press charges - all the robbers wore masks - and so he decides to track down the thugs and claim a share of the cash for himself. You get where this is going early on, but when you see Jack Elam and Lee Van Cleef on the cast list, you know that you are in for a bumpy ride. There are plenty of crosses and double-crosses as he and the gang (none of whom know the identity of their criminal mastermind) try to get to Mexico and to the loot. It's a good end-to-end action adventure, with a taut, eery score from Paul Sawtell adding much to the sinister lighting effects that give this film a much better than average sense of suspense.
