An acting troupe rents an oceanfront mansion to stay in while they get ready for the show. Before you know it, the star of the show has disappeared and a fellow actress is found murdered. The situation seems grim.

Luckily, one of the cast members named San Toy has an idea: "I met a detective. The world's greatest detective. His name is Jimmy Chan. Great Chinese detective. He'll protect his countrywoman."

Soon Jimmy Chan is on the case, accompanied by associate Birmingham Brown, and you know that Charlie Chan himself cannot be far behind. Sidney Toler moves a little slowly but is wise as ever in his final appearance as the great detective. Sen Yung and Mantan Moreland are energetic if not exactly inspired as Jimmy and Birmingham.

The supporting cast is pretty standard and features an assortment of young women who seem to be designated by type (the French one, the hysterical one, the cute flirty sarcastic one). The suspects, of course, all accuse each other of murder and lesser crimes, and it's up to Mr. Chan eventually to sort it all out.

The whole thing appears to have been put together pretty quickly, and I'm not at all sure the plot makes any sense...but it's undeniably fast moving and contains a bit of humor. There are also some great shots of oceanfront highway and beach in the picture's opening moments. For those who are not sticklers for tight plot or strong production values, this picture is actually a lot of fun.

'The Trap' is better than 'The Scarlet Clue', it reminded me of certain mystery movies with Gabin (they were Maigret mysteries), 'The Trap' is more psychological, in its modest way, it's also heartrending, and we know that it is the last time Toler, as he was by then approaching his end, plays the great detective, this time a puzzle plot on Malibu Drive, and many girls, caged; after the denouement, there's a heartbreaking scene, Toler leaving, saying goodbye, and the whole movie has these asides (about race, the movie's own style, etc.), with a self-consciousness less used before. The movie takes an interest in a different type of case: more psychological, and this also expresses the limits of a Monogram script.

Its style and plot is very much that of Monogram's mystery comedies. This movie doesn't resemble the others in at least a few respects: no technological concerns (aside from the garrote), a straightforward mystery, and we get actually less of Birmingham and the son Jimmy (some seem to believe that the assistants took over much of the action in Toler's final movie, but they obviously didn't, in fact we get less of them). Each movie provides a location for the assistants to wander through; in this one, it's a cellar.

Sadly, this is one of the weakest Charlie Chan movies (though even at that, it provides good, average B movie entertainment) - and even much more sadly, it was the last film that Sidney Toler could finish before he died. There are moments where it's obvious that he struggles with his fatal disease; which makes the whole thing even more sad, but also increases enormously our respect for this great actor who gave everything literally until the end.

The story is somewhat confused, the movie seems like it's been done hastily (perhaps because Sidney Toler didn't have much time left?); and the hysterical crowd of 'bathing beauties' certainly tends to go on the audience's nerves, even though they display the latest and most daring bikini fashion of the time. There's a variety troupe on holiday at the seaside, and it becomes clear very soon that the 'star' of the group is SO unsympathetic that sooner or later she WILL be killed... But first it's one of the other girls' turn, whom shrew Marcia blackmails into stealing papers from another girl's trunk (threatening that she'll reveal that the girl is under age), so that she can blackmail the other one, too, whose husband seems to have a dark past. The little girl is strangled, and her Chinese colleague San Toy (one of the few nice girls of the troupe) calls on her friend Jimmy Chan for help - in somewhat of a confusion, so that Birmingham, who picks up the phone, is under the impression that Jimmy has been murdered!

So he and Charlie haste to the beach house, where they soon catch an intruder: Jimmy, who found the paper with the address on Birmingham's desk! No need to say that Charlie is immensely relieved; but now he's in the middle of a murder case, of course - and, as was to be expected, the next day on the beach the body of hated Marcia is found... Now everybody starts accusing each other, some of the girls get fits of hysteria - and Charlie, together with his two assistants, tries to make head or tail of the whole muddled case.

As I said before, this movie certainly isn't among the better Charlie Chans - but it's our last opportunity to see our beloved trio Sidney Toler - Sen Yung - Mantan Moreland together; so let's just enjoy the jokes and the suspense, and laugh and let's be entertained by them once more...
