G@me (2003)

A high flying executive stumbles across a damsel in distress, she is actually the daughter of a major client who is the man behind a massive project on which he is working. The girl gives him the impression she needs some time away then suggests casually that they fake her kidnapping and split the ransom. When the project falls through he decides to take up her bizarre offer for personal as much as financial reasons.

In any kidnapping for ransom the pay-off is always the fly in the ointment, but our hero is also a games developer, and his knowledge of technology - including disguising his voice electronically - is second to none, so with that and a little old-fashioned artifice, that hurdle is negotiated safely.

All good and fine up to here, likewise when it transpires the damsel is really a femme fatale, but hereafter the plot becomes so convoluted that you really have to wonder what is really going on, and the ending, well, if you watch it without the subtitles, you won't be any more confused.
