Mechanic: Resurrection (2016) on Netflix

Plot summary

A courier named Renee Tran tracks Arthur Bishop to Rio de Janeiro, where he keeps out of sight under the alias Santos. Her employer wants him to kill three targets and pass the deaths off as accidents. Bishop escapes her and travels to Thailand, taking shelter at the beach house of his friend Mei, where he finds out that Tran answers to Riah Crain. On the water, Mei sees a man beating a woman and calls on Bishop to help. The woman, Gina Thornton, runs a children's shelter in Cambodia. Crain's men seize Bishop and Gina, and Crain makes clear that Gina lives only as long as Bishop keeps killing.
