The Young Tycoon (1978)

Pavlos Dellis, a young, handsome, and self-made shipowner, doesn't have much time for love. As a result, the rapaciously ambitious businessman prefers to pay for sex, with Werner, a photographer and owner of an Athenian model agency, and his girlfriend, Samantha, making sure that Dellis is never short on beautiful, high-class call girls. In the meantime, statuesque Tina, a wealthy brunette spending her summer vacation at the same luxurious seaside resort, finds herself increasingly enchanted by the self-assured playboy, and without much thought, switches places with Samantha. However, after the brutal murder of a young woman, paired with an unaccountable disappearance, Dellis ends up being the prime suspect in an unsolved murder. Undoubtedly, Dellis is a self-centred cynic; but, is he also a killer?
