The young man who calls himself Catch could turn out to be a deranged type who saved Sharon only to kill her himself. Or perhaps he's some sort of guardian angel whose time on earth is limited. It is instead an unusual love story that presents Lopez and Caviezel to advantage, thanks to sensitive writing and direction by Gerald DiPego and Luis Mandoki, respectively.
Catch is, however, decidedly strange.
He's a tall, nice-looking man who wanders the streets of Chicago in a long overcoat looking for opportunities to perform random acts of kindness. He has a shellshocked quality that makes it seem he has experienced a major trauma in the past. In short, had not Catch saved Sharon's life, she probably wouldn't have given him a second glance, let alone finding herself inviting him up to her apartment when their paths cross again. If at this point Catch is something of a mystery, to say the least, Sharon is another matter. Surely, Sharon's action had much to do with propelling her into police work.
