Bird on a Wire (1990)

Rick Jarmin (played by Mel Gibson) witnesses a murder committed by a powerful drug lord named Eugene Sorenson (played by David Carradine) and his henchmen. Fearing for his life, Rick enters the Federal Witness Protection Program and assumes a new identity as Jack Bird, living a quiet life teaching history in a small Oregon town.

Fifteen years later, Rick's former girlfriend, Marianne Graves (played by Goldie Hawn), is now an ambitious attorney working on a case involving illegal toxic waste dumping, which leads her to discover Rick's new identity. She tracks him down and confronts him, causing him to unintentionally reveal his true identity to his loyal dog, Archie.

Marianne convinces Rick to assist her in her case against the corrupt company responsible for the toxic waste. As they try to gather evidence against the corporation, they discover that Sorenson, the drug lord who tried to silence Rick years ago, is also involved in this case. Now, both Rick and Marianne are being pursued by Sorenson and his goons who are determined to silence them permanently.

Rick and Marianne embark on a cross-country escape, constantly on the run from Sorenson's men. They encounter various obstacles and comedic situations along the way, including a hilarious encounter with a crazed dentist and a daring escape from a high-rise building.

During their journey, Rick and Marianne reignite their past romantic feelings, despite the challenges and danger surrounding them. Their chemistry and the adventure they find themselves in bring them closer together.

As they move forward, Marianne decides the best way to stop Sorenson is to expose the evidence to the media. They manage to reach a news station, where Marianne plans to present the evidence. However, Sorenson's men arrive and a hectic shootout ensues.

In an intense and action-packed climax, Rick and Marianne use their wit and resourcefulness to defeat Sorenson's henchmen. They finally manage to broadcast the evidence on live television, ensuring that the truth about the toxic waste and Sorenson's involvement is exposed to the public.

With their mission accomplished, Rick and Marianne successfully evade Sorenson and his men, who are subsequently arrested by the authorities. Rick decides to leave the Witness Protection Program, knowing that Sorenson's empire has crumbled, and returns to his true identity.

In a heartwarming conclusion, Rick and Marianne embrace their feelings for each other and decide to start a life together. With the villains defeated and justice served, they bid farewell to the thrill of their adventure and look forward to a future filled with love and happiness.
